Easily the best suggestion here.
Like others have said, it depends on your personality type - do you like to work in groups? Do you prefer to work alone? Are you a people person who loves helping others? Are you the analytical type? Or are you a man of the night who enjoys taking your clothes off?
I'm actually going through the same thing as you right now being bored with my work in finance, and planning some future careers in Forex trading (which only requires a few hours per week) and studying criminology. I also have a passion for coffee, so interested in doing just a few hours a week in this industry, maybe coffee roasting. I'd like to have a few different jobs to make each week more interesting.
That's maybe not the answer you're looking for, but just providing some examples of how to think of the things you love doing and applying yourself towards a new career(s). Find what you're passionate about, something that inspires you.
