Take that space between perceiving something and letting the words come out from your mouth to criticize and make it more productive. Create something.
Give yourself reasons to make something. Even if it is something small. Everything big usually comes from something small. It’s easy to say, “This is not nice, it is not tasty, it is not right.”
What is difficult is to say, “This is what I did, how do you like it?” and be vulnerable. Ignore the need to pretend you are adding value by criticizing. Instead pick up a pen and start writing. Or a brush and start painting. Or some money and start a business.
Create don’t criticize.
