Where to start?

I am a 20 yo guy that is living at home pretty much till the end of the year. I have always enjoyed being my own boss in almost any situation. I'm not great at it, but I prefer it. I've had entrepreneurship opportunities in the past, where I made crafts, things from birdhouses, wire twisted art, and origami nativities.
I am currently working a job that I don't particularly like, and I want to grow and give myself a chance for something better than this in my own future.
What are some ideas for things I can do before the year is over that might actually help me learn something about entrepreneurship or help me make money in a way I might enjoy?
I want to make the most of the time I have left where I'm not paying rent, and I am paying minimal bills so I have an easier space to learn in before I am fully on my own.
