Everyone is their own worst critic.
I can pick out mistakes I made on a project, team or code a mile away. Heck I’m looking at flooring I laid down and there might as well be bright red ink painted around all the mistakes I made in what I installed.
But when other people look at the finished product, they don’t see them. They probably don’t see them until you point them out. And even, they are in the tiniest of corners that they make little to no sense as to why you are worrying about them.
These are the mistakes we make, they stick out like a sore thumb or fat lip, to us. But to everyone else, they are perfection in the making.
Don’t let the mistakes you make hold you back from the great work you can accomplish.
