Zapraszamy na trzy dwudziestopięciominutowe rundy medytacji, w trakcie których będzie okazja doświadczyć swojej pełnej obecności w tym-co-jest z-chwili-na-chwilę. Rundy rozpoczynamy o 18:30, 19:00 i 19:30 - można dołączyć do dowolnej z nich lub odłączyć się w trakcie przerw pomiędzy nimi. Prosimy o przyjście chwilę przed rozpoczęciem rundy, ponieważ startujemy punktualnie. Medytacje odbywają się w każdy czwartek na ul. Zielonej 30 w Łodzi w lokalu HSŁ w głębi bramy. Przy bramie prosimy dzwonić pod numer: 42 203 20 50. Spotkania są otwarte i wszyscy są mile widzani. Jeżeli chcesz zobaczyć, czy medytacja to coś dla Ciebie, temat jakoś z Tobą rezonuje, a może już praktykujesz, przychodź! Zorganizujemy coś, na czym można usiąść, ale dobrze jest wziąć ze sobą swoją poduszkę do siedzenia lub matę. Do zobaczenia!

Zapraszamy na kolejne spotkanie planszówkowe! Mamy parę gier w spejsie, ale zachęcam przynieść również własne gry! Chętnie zagramy w coś nowego. Jest też miejsce na zostawienie gier na jakiś czas w spejsie, żeby nie musieć ich targać tutaj co tydzień. \-\-\- Zaczynamy o 19:00, ale warto sprawdzić [https://at.hs-ldz.pl](https://at.hs-ldz.pl) – być może ktoś otworzy siedzibę wcześniej. Jeżeli masz problem z wejściem, zadzwoń na 42-203-20-50 albo wejdź na naszego chata (patrz poniżej). Potrzebujesz więcej informacji? Skontaktuj się z nami na czacie lub mailowo.

Początkowo freelancer, obecnie Flutter dev w brytyjskim startupie Cheddar. Lubi ładne designy, czysty kod, i delegowanie jak najwięcej do LLMów.

This training is designed for real estate agents who want to learn how to play the Agent Investor game. The goal of this training is to help you flip your income into ownership. ━━━━━━━━━━━━━━━━━ **Investors move fast. Most agents don’t.** If you can’t evaluate a deal quickly and confidently, you lose credibility—and the opportunity disappears. Deal or Disaster teaches a simple, repeatable framework to determine in minutes whether a deal prints money or burns it. In this session, you’ll learn a 5-minute investment evaluation system that works across flips, rentals, BRRRRs, wholetails, and creative deals. The goal isn’t perfection—it’s speed, clarity, and credibility. We’ll break down: * How to identify the investor’s true goal before running numbers * A fast, reliable method to estimate ARV with confidence * How to calculate the real all-in acquisition cost * Simple heuristics to ballpark rehab and improvement costs * The key metrics that reveal whether a deal works—or should be killed You’ll also learn the most common red flags that signal bad deals, thin margins, and hidden risk, so you know when to pause or walk away. When you can analyze deals in minutes, you earn authority, build trust, and become indispensable to investors. Speed creates opportunity—and opportunity creates repeat business. If you want to move from real estate generalist to trusted investment strategist, this session gives you the framework to do it. ━━━━━━━━━━━━━━━━━ **Did you miss it?** [Watch all GRID Reston event playback on YouTube](https://www.youtube.com/playlist?list=PLOTh5kxLLJI1G3VH6Pqhlhu0uTA8yrdpi) ━━━━━━━━━━━━━━━━━ **Join the GRID Facebook Community** [Join the online GRID community here](https://www.facebook.com/groups/gridinvestor) to post deals, ask questions, and connect with other investors across the globe.
