What are the three most critical principles early-stage founders consistently ignore?

2026-02-11 · Lounge

I keep repeating the same three things because they keep being ignored:

1. Collide your idea with reality ... before you build. Opinions don’t count—behavior does. 2. Focus beats ambition. Do one thing shockingly well before you do anything else. 3. Watch your cash. Everything else—vision, culture, hype—depends on not running out.

Founders who internalize these win sooner.
