Perfect is the target that keeps getting further away.
Imagine shooting an arrow at a target. From afar you hit the dead centre.
Then you get closer and you realise it was off by a few millimetres.
Should you still count it as a bullseye?
You shoot again. This time closer. Only one millimetre from dead centre.
You shoot a third time. Half a millimetre off.
How long would it keep going for?
The more you shoot, the closer you get. But each time you inspect the arrow, you find it to be off by a little bit.
You realise you're never going to hit a perfect bullseye. You could give up.
You could remind yourself of this every time you shoot and be relieved of the pressure. The pressure to be perfect.
Don't let perfectionism get in the way of progress.
