Starting things, but not finishing

Hi Brooke!
I’m working on my homework this month and I wrote down my purspose, but it feels very broad and I feel like I need to pick up something small and realistic instead.
I’m concerned, since I have a tendency to start things and than not following through. I started ceramics classes but than stopped. I got yoga certification but than never done anything with it, but I got thai massage certification but also never done anything with it, I took a real estate class but never really did anything with it neither.I love all of those things and they genuinely make me happy and I really enjoyed the classes, but I feel like I haven’t done anything with it out of fear of failure.
Would it be better to pick one of the hobbies as a subject of the homework?
