For most people who aren't independently wealthy, it takes steady income to keep a life going. So how would ideas about a side project help you do that? What makes you think ideas are worth money? Is there anyone else you know who has sold similar ideas in this manner? Are you a famous physicist or politician? I'm asking hard questions not out of meanness but out of genuine concern to get to a more stable track forward.

If one has under-treated conditions like OCD or manic depression, I've seen people with unhealthy fixations on ideas be their own worst enemies and sabotage their life situations. People who lived in vans but failed to get medication and floated in the in-between and on the margins. I've been there. There's no reward for misery and it's difficult to climb out of it. Wash windows, sell t-shirt, mow lawns.. all things that can be done with minimum of resources for immediate cash. Go on craigslist and offer technical services for an hourly rate.

It's not enough to want. One has to sustain themselves, be relentlessly resourceful, do and build something people need, and collect money in one stable way before changing to another. Stability first. It's like an investment portfolio: you wouldn't throw your parent's life savings into a random NFT. Maybe $5 as a test, but that's it.
