Perfectionism is not a good trait if you allow it to block you from taking risks and trying new things in order to move forward toward your goals.
Because what happens is that you criticize yourself at every single step, and you stumble, and you stumble, and you stumble, only to keep hearing the echoes of that criticism.
Perfectionism is helpful once you are already moving forward—once you have taken a step, discovered something, and now need to refine the concept, the direction, and the goal to make sure that it’s working. That meticulousness is going to help you to really get it right.
Use perfectionism wisely.
