While ideas such as discipline and focus are undeniably important, so is the idea of having fun. With a small amount of effort, we can extract all the fun and joy out of most parts of our lives--our relationships, our work, even our leisure time. We can put so many restrictions and should's on everything we do that our very lives become dull, overly ponderous, and routine. Before long, we find ourselves living up to a set of rules--and we're not certain where the rules came from or whose they are. Let yourself go. Have a little fun with life. Or, have a lot of fun with life. If you've spent years being extremely disciplined, reliable, and somber, maybe part of achieving balance is having a decade of fun.
