Everyone struggles with what is actually good enough.
Not because we all have different levels of what we feel is “actually” good enough but rather because we are at our most critical when trying to decide if our work is at the stage of being good enough to show others.
“It doesn’t do these seven things”
“I need to make one last edit”
“I think it should be red, not orange.”
Your good enough, my good enough are very different. The best way to get past it is to ask for someone’s opinion, what do they think (and pick someone you trust who has like standards).
If they tell you it’s good enough, put it out there, if they don’t and you thought it was, good to know, go fix it.
Just make sure you don’t hold onto for too long so it goes beyond good enough and into took too long to show.
