I am a small business owner in a creative field, and while every day is not all unicorns and butterflies, it challenges and energizes me. I'm currently researching another different direction to go. I love working for myself (though of course any client or customer is your "boss") and setting goals.
24 is still very young!! You have the passion, you have the desire, now find what you want to do. Have you tooled around on Etsy to see what others are doing craft-wise? What ideas do you have? Are they marketable? Can you find enjoyment AND make money dong what you love?
Good luck!
