Leaders are Readers. Readers are also healing in the process. We are who we surround ourselves with and each book we read creates one of those people we surround ourselves with. It's a life hack in order to be at that persons level. Which is important because if you hang out with 5 millionaires you'll be the sixth one. If you hang out with 5 people know found there purpose you'll be the sixth one to find your purpose.
Look for books that will educate you on what your trying to learn. Internally and Externally. For example if I want to get better at helping people I'll read "Dale Carniege's How to win friends and Influence People" if I want to get better at removing my social anxiety I'll read "Ellen Hendriksen's How to Be Yourself" if I want to make more money I'll read "Napoleon Hill's Think and Grow Rich".
Reading is Key. Another good reason for this is if you grew up in a dysfunctional family and didn't have the right guidance growing up will lack the skills of how it feels to be loved and raised with a healthy view of the world. Books for me became my parents and I got to reparent myself through them. Knowledge is Power and when you apply it you get Wisdom.
