How to Get Over Losses and Betrayls & Build Lasting Relationships
Join us for this free, in person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships.
Do you want more motivation and confidence to build lasting relationships?
Are you burdened by a stressful relationship?
Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse.
Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival, while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well.
Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship.
Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action?
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships!
Break free from self imposed limitations
Here we will discuss:
• How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes.
• Why and how do the negative emotions of others affect you?
• Why is my partner withdrawing and what can I do about it?
• Why do we sometimes feel compelled to hurt the ones we love?
• Fights & arguments - what's really behind them?
• What underlies “corrosive criticism” or the need to invalidate self or others?
• How one can stably change one’s outlook on life so they can affect positive change?
• Where do compulsive destructive behaviors come from and what can be done about them?
• How to form closer bonds & keep growing the relationships with the people you care about?
• How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career?
Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general.
Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person.
Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life.
We look forward to having you join us!
This class is held at the Dianetics and Scientology Life Improvement Center of Central Ohio.
Stop Negative thinking and Over-thinking and Feel More Positive
How do we recover from having had a toxic or narcissistic ex?
How do we move on from the past, especially something as traumatic as a divorce or breakup?
How do we avoid anxiety and depression?
How do we have more self esteem?
In this meeting, you will learn the mental health secrets to help you
quickly get over the past and heal your mind.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Dianetics & Scientology life improvement center.

Morning walk at Scioto Audubon Metro Park
Join Losing Weight in Columbus for a late morning walk at the Scioto Park!
We'll meet up by the climbing wall at 12:30 and go for a moderately paced walk. We will aim to go for an hour, but can cut it shorter if needed.
This will be a casual, but active walk where we chat with each other, discuss goals, and have some friendly banter along the way!
Arthouse Friday: THE DRAMA at the Drexel Theatre!
Join us as we get together for an Arthouse Movie Friday event to see the A24 dark comedy /romance / psychological-thriller, THE DRAMA! The film stars Zendaya and Robert Pattinson as a happily engaged couple whose relationship is challenged when one discovers unsettling truths about the other. Here are details, a trailer and our plan for this event:
DESCRIPTION: The film follows a happily engaged couple whose relationship is put to the test when an unexpected turn sends their wedding week off the rails. The film comes from A24, is written/directed by Kristoffer Borgli stars Zendaya, Robert Pattinson, Mamoudou Athie, Alana Haim, Hailey Gates and Zoë Winters.
ZENDAYA-PATTINSON TRIFECTA CHALLENGE: Robert Pattinson and Zendaya will star in THREE movies together this year, including THE DRAMA, Christopher Nolan’s THE ODYSSEY this Summer and Denis Villeneuve’s DUNE: PART THREE at Christmas!
TRAILER: [https://www.youtube.com/watch?v=6zmKcUa4Xxk](https://www.youtube.com/watch?v=6zmKcUa4Xxk)
BUZZ & REVIEWS: Overall some solid early reviews but this one seems to be a bit polarizing! We’ll have to see for ourselves. Those in the “loved it” camp say is not the rom-com the trailers would have you to believe! Instead, a twisty darkly comedic drama that’s “anchored by two compelling performances,” “an original idea, great cast, and a movie that’s gonna have people talking at the end of it!”
PLAN: A slightly later showtime so we’ll go with dinner before the show this time. Here’s the plan: For dinner before the movie, meet at nearby BRASSICA between 5:45 and 6:00pm. Go through the line, and we’ll try to snag as many of the high-top tables as we can. For the movie, please purchase your ticket for the 7:30pm showing and we’ll meet in the lobby area between 7:00 and 7:15pm. I’ll be with the dinner group and will try to get there as close to 7pm as possible. Advance ticket purchase not required for this theater. When you purchase yours at counter, be sure to mention you’re with the Movie Group for admission and concession discounts.
Take care and look forward to seeing you there, Dan

Humanist Program
The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event.
We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be.
Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk.
Going forward our meetings will be hybrid. You can meet us in-person or attend online

CBusData: The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again.
We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all.
Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
