Day 9 of going full time on my project. Today sucked

Failed a freelance interview today. Frontend role. I know this stuff, I've been building full apps for years, but my brain was completely fried. Couldn't think straight. Fumbled through answers I normally nail in my sleep.

That's the part nobody warns you about going full-time solo. You're coding all day, doing outreach, writing content, making every decision yourself — then you jump on an interview as your backup plan and there's nothing left in the tank.

The stress hits different when your savings have an expiration date. €10K left.

On top of that I wasted most of yesterday building a Stripe integration for my MRRSaver. Got it working. Felt proud for 10 minutes. Then realized my app isn't even finished. No cancel flows. No onboarding. Nothing for it to connect to. Built the plumbing before the house has walls.

I keep thinking about starting a small dev agency on the side. Building MVPs and landing pages for other founders. I can build a full product in a weekend with AI now. Why not get paid for it while my SaaS grows?

Not because I want to. Because runway matters more than pride.

9 days in. Already built the wrong thing and bombed an interview. But I'd still rather be here than back at a desk building someone else's product.

Anyone else juggling "build my thing" vs "survive financially"? How do you handle it?
