Hello @benainouna :)
It is wonderful to hear from you. I am very pleased to hear you liked this article.
I use to say that the first and promising step to change this sort of thinking is actually to realize that this is one's case, which you have done :) from here onwards, it is a matter of practicing the non-judgmental aspect of your thought process and becoming more proactive about what makes you feel good.
But, you are right! I should write a post about positive thinking :D
Thank you for the idea. You take care of yourself!
