Mechanical Engineering or nursing/doctor?

I'm 21. Not a sob story just context. My life situation right now is not the best I'm kind of confined to my parents house no car, no transportation stuck in a different state because of my other parents situation and I am not landing a job.

Point is Although I have no particular interest in it I want to go to community college for my associates at this point so I'm not doing nothing and being a bum. The most appealing choices to me are ME and Nursing (particularly cause i want to make money it's a big issue in my life right now) I also liked the idea of sports management and being a doctor but management doesn't have a lot of job opportunity's I've heard and becoming a doctor is a very long time commitment for someone who only likes it but isn't fully in love with the idea of it.

I would just like some guidance and help on what i should pick or do? particularly from people who have done it. My goal is to get my associates land a job and live with my parent on low expenses while still making my own money. And just really save and invest until I have the financial freedom to purse things.

(Sorry if this is the wrong form for this)
