How to reprogram your mind?

It's a difficult question because there's no easy answer. If somebody asked you "How to reprogram my computer?" how would you respond?
A human mind works like a computer. It takes a lot of time and effort to learn how to reprogram both of them. I'm not a programmer, but sometimes I write simple AI programs for fun. Mostly for board games like chess. It's a good exercise.
Can you write a simple "Hello World!" program in any programming language? Can you write a program, that adds two integers? If your answer is "yes", then how comfortable would you be to recompile your kernel?

There's no simple technique to reprogram your mind. There's no easy trick to it. I'm not going to sell you affirmations, visualizations, hypnotic recordings, etc. I'm going to write about hardcore reprogramming of my mind, and describe a lot of specific algorithms.

This skill requires logical thinking and algorithmic thinking. It's programming after all. But just like computer programming, it gives instant results. When I feel that something is wrong, I can look into my source code, fix some bugs and instantly feel, think or behave differently. Within seconds I can solve psychological problems, which would take years to solve otherwise.

My answer to the question "How to reprogram your mind?" is:
It's a skill - you have to learn it.
