Great article from 99U about getting over perfectionism.
Studies show apparently that if you are allowed to make mistakes, you make fewer of them.
We approach tasks with 2 different frames. The first is where we want to prove ourselves capable. The second is a learning/improving frame.
The first generates worry/anxiety when the task is difficult or unfamiliar which undermines performance. We are also less likely to be creative or innovative and can quickly become demotivated.
On the other hand, framing a task as a learning experience means you can’t actually fail, so the pressure is off. We are free to explore and experiment.
It’s a good read with some excellent suggestions:
