You need three things to create a startup: enough food, a place to stay, and clothes to wear.
If you hustle is online, you can include an Inet connection and a coding agent (like Kimi on #Opencode or just BigPickle); and a couple of books (more on that later).
If you fail that's your problem. Harsh, but fair.
Take a bike. Take a ride.
It's a risky business, by definition. You do not need to feel bad about it. It's the nature of the beast.
Sip some wine. Some cheap wine for the moment.
Now (re) think; if you fail and you manage to keep having food to eat, a place to stay and some clothes to wear, then you are good.
Understand your failure, from first principles. And just give it another try.
Think, experiment, build it again, ship it again and try not to fail again.
Above all, try to stay alive.
It's a fascinating game. Enjoy!
