Understand that at the end of the day, it is a job. You will eventually get bored on some level of anything you do. It can be exciting to learn something new, but before you do, you should be okay with boredom, too.

Existentialism is heavy stuff for what is ultimately a job at the end of the day. You don't have to wrap your identity up in your job or whatever your current role or project is. If it pays the bills, great! It's a CRUD app? Fantastic!

If you want to start your own thing and your partner is on board, and y'all have the runway for it, great also! But since you said you have no great ideas, yet, you may want to hold off until you do. Starting a business is exciting at first but turns into a grind at some point, too. You'll have to go through lots of drudgery when you run your own company. Make sure you're okay with the boring stuff.
