Is Not Wanting To Work For Anyone Anymore Enough Motivation To Start Your Own Business?

Hey guys, my whole working life I’ve always had a great work ethic, I can run laps around people at the jobs I’ve had. That is, if I want to. No job has ever been fulfilling, I’m always thinking of how management could do better or “if this were my business..” type thoughts. I’ve been tired for a long time now of all of these thoughts, and the other politics that come with working under someone else as well as seemingly being undervalued and overworked while the shit heads at the job get off easy. I know how employees should be treated and I know how to practice ethical and moral practices and still run a business, as opposed to nearly all of the businesses I’ve worked for. Is this enough motivation to start my own business? I’m 27(f), and I’ve had numerous business ideas since I was a teenager but I’ve never pulled the trigger due to what I’d say is fear, and excuses for myself like how am I going to pay bills while starting a business. But that’s another topic. So, is my heart in the right place as far as motivation goes?
