To learn, to move forward sometimes you just have to take some weight off the result.
After you start learning you accumulate things you might not need, as if your mind is a house you need to clean it up.
Cleaning it up at first might seems like destroying something.
In fact you start removing things you initially thought were important but now are just useless.
It’s like saying goodbye, so you need to learn how to do it properly without getting emotional.
Destroying part of your work is sometimes a good thing.
