Good starter, bad finisher

I have a thought that I am a bad “finisher” and that I always start new projects and move on to the next thing when it is no longer super exciting.

I am closing in on a project launch that I have been beta testing with a group of people for 10 weeks. I’m starting to think/feel that this is not what I want to do. Why? Not because I don’t think I can. I know I can make it successful. But I am thinking thoughts that make me feel like it’s boring. I can’t say “I don’t know” what I want. I know what I want to do! I want to quit this project and start a new, shiny one.

But how do I know if I am quitting this project because it doesn’t feel exciting at the moment and I think it’s “supposed to be exciting and fun all the time” (50/50 life issue haha), or if I’m buffering by sticking with this project because the new project is uncertain and riskier?

I know it doesn’t serve me to think I’m a bad finisher… I just struggle to see if I “like my reason” for quitting.
