The experiences you have form the references you use to make decisions. The more knowledge you have about a topic, the better the decision you make about it will be.
Focus on learning.
Knowledge is power, and the more you learn, the better informed your decisions will be. Take on new challenges and try to learn as much as you can.
When you can’t go out into the world and learn about a topic, read a book about it instead! Learn from someone else’s experience.
