I'm going to cheat today and talk a little about Playing. I'm going to be 56 next year but seriously I'm a big kid. I rasied my kids in later life on my own so naturally I went to work everyday and then went home and did wash, cook and dishes etc. But guess what I certainly didn't like it. Many a day I'd look out my office window and wish I was in a park, at the beach or just napping along a stream fishing.
Now that the kids are older and work has learned it better learn to get along without me now and then I can play. Who cares what it is, a video game (Don't tell my kids), or any other fun thing I can think of when I'm not a dad or a boss. It charges up my batteries, clears the head and then my creative juices can flow.
Rule #15 Pretty simple learn to Play!
