To stop overthinking. I haven't managed yet how to defeat this but I am working on it. Overthinking has good and bad sides, you are always prepared for the worst situation, that's a huge plus, but the bad side is that you are expecting the worst all the time and you are kinda in a neutral position and holding there so nothing bad happens to you, but, good things are out of our comfort zone. So I hope I can manage and master it well, if anyone can do that then they will build very strong mindset.
