Being as close to perfect is great for something’s but it is slow. Really slow.
You could spend weeks prepping for a meeting. Hours prepping for a cold call. 10’s of minutes writing an email. But, that would take far to long and you have too much to do.
It not a waste of time but it is an inefficient use of it. Do it fast, do it bad, improve it if you have time and if it matters, if it doesn’t don’t.
Don’t quit and don’t let peoples opinions of your bad pitch or website get in your way it’s feedback to improve so take it but leave it at that.
Get the first draft out, get stuff done and move on.
