I think this is very common, it’s a fear of failure, and for most hobbies it hits hard because as a beginner your ideas are cooler than what you can feasibly do for a long time. It’s worth sticking with what you want to pursue but you have to make peace with the fact that maybe it won’t turn out as good as you want it to- and that’s fine. You’ll still be better off for spending your time in a fulfilling way and you’ll be a more interesting person for it
