Today, I realised something.
You have the right to screw up.
No one is allowed to violiate this right.
No one, not even yourself. You must invoke your right to screw up. You don't have to be perfect, and neither does what you make or do. So don't force yourself to -- don't violate your own right to make mistakes. Mistakes are good for you. Without them, you will not reach your goal.
You have the right to practice -- you don't need to be perfect right away. In fact, most people, yes, even really talented people, have to screw up at least 500 times (or more) before they can be even nearly perfect.
So go on now. Do what you've wanted to do -- be it photographing, writing, painting, singing, playing the piano, kissing your neighbor, smiling at strangers, baking lasagna, meditating, running, badminton, driving, composing, or advanced math. Practice. Practice, practice, practice! Make every mistake you can possibly make! That is your right.
Remember G.K. Chesterton: If a thing is worth doing, it is worth doing badly.
