Sounds like you might want to start a lifestyle business. You should read and listen to everything by Rob Walling, especially his “stair step approach”. Wish someone had told me this at your stage.

For meeting founders, find someone in the area you’re interested in and build stuff with them. Also consider using the YC founder network, but they may be too ambitious for you.

Lifestyle businesses are probably less dependent on cofounders for success.

You’ll need to work hard at your tech skills if they’ve atrophied. The good news is, this part is incredibly fun.
