One of the best life lessons I learned was while perusing a poker strategy book in a bookstore as a teen. I’ve never been into poker, not even sure why I picked it up. One thing it said was the most important thing to remember is that most of your hands will be crap. Don’t get attached to a bad hand and don’t convince yourself that an ok hand is a good hand. If you just fold the bad hands and play the good ones you’re already a better player than most.

I took that to heart and it has served me well in life.
