The #1 thing you should learn, the #1 thing you must learn, and the #1 thing that will help you be better in everything you do is learning "how to learn."
Some people may think whats important to learn in life is business (if they are focused on business), others will say productivity so everything is faster and more efficient, parenting may come to mind for some because that is the evolution of humans. But the reality is the best thing you can learn is "how to learn." Learning "how to learn" will help you in many aspects in your life.
