How to recognize when to stop or to continue?

I have had a hard time since last year keeping faith and staying motivated on my professional goal.

Some people told me I’m too perfectionist, that I’m trying to do too many things in my business. I think all these things make sense in the business, and I have always been interested in different things.

But I recognize that it is too much for one person. I get overwhelmed and discouraged. Often I get very anxious and I ask myself if my goal is achievable. If it is, I don’t know how. My thoughts are I’m not good in business, I don’t know enough on the business side because I’m a designer, alone it is not possible. I have been stuck for a long time and it is getting more and more of a problem for me.

Does this mean that this project is just not right for me? Or should I continue? But how?
