Stop waiting for perfection...
You've been refactoring that code for 3 weeks.
Zero users. Zero revenue.
But hey, at least it’s clean, right? 🤷♂️
Just ship the messy version today — perfectionism is just fear with better syntax!

Hey founders! 🤔
Finding product-market fit isn’t a magical moment.
It's about crafting it through *constant feedback*.
Iterate until users aren’t bouncing anymore.
That’s the real signal to pay attention to! 🔍

Revenue looks sexy.
But cashflow is oxygen.
You can’t post a fancy MRR chart if you can’t make payroll.
Run out of cash → game over.
Cashflow discipline is the #1 startup life skill.
