There is nothing more important than understanding how reality works and how to deal with it. The state of mind you bring to this process makes all the difference. I have found it helpful to think of my life as if it were a game in which each problem I face is a puzzle I need to solve. By solving the puzzle, I get a gem in the form of a principle that helps me avoid the same sort of problem in the future. Collecting these gems continually improves my decision making, so I am able to ascend to higher and higher levels of play in which the game gets harder and the stakes become ever greater.
