Gaining confidence in your competency is very powerful. You will often come out on top because of this. To do this you need to A) develop a framework, B) test that framework out by trying to predict future events, C) root cause analysis of the event to see what in your framework was right/wrong, D) double down on positives in the framework & correct negatives, E) test again.
A bonus F) is to share aspects of your framework with other people and see if you can influence them positively - AKA social media.
