Do you sometimes feel like you do well in life then something happens and you slide back, never quite getting ahead. At this Meetup you'll find out how to identify what actually causes the lows, the highs and everything in between. More importantly you’ll get the secret of how to gain control over your life so the highs are higher and the lows go away. Wouldn’t it be nice to stop the wild roller coaster ride for good? Or at least make it a fun roller coaster ride, with more ups and downs. There is a hidden factor that will be going over and you’re going to be quite surprised what it is and how much it affects your life. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This group is hosted at the Dianetics and Scientology Life Improvement Center.

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp.
