For me my greatest motivation was that I wanted to work with people individually, money be damned. I had a supportive spouse and we already lived frugally so I could build a business without (overwhelming) fear of failure.
If you can still stomach office work become an accountant. You’ll use all your analytic skills in a role that is useful to every sized company but your pace of work will be much more constant. Your ability to write small programs and debug excel will make you valuable.
