You can't. Better not to work at big corp. I did that for 16 years and everyday I was miserable. High performer, always but big stress. I had chronic back pain.
One day, I simply quit and started my business. We are doing $200k in MRR now with two of us. Business is mix of software and physical store.
My suggestion is to work on and for yourself.

That sounds like the dream. I just need to think of any idea like that
That's a risky way to do it. Start something on the side and get it going generating positive cash (validated) before jumping ship. Not doing so risks bankruptcy and lots more stress.
Ideas aren't profitable, only that which is shipped and paid for by customers is.
