People are often too busy to have fun. They have to pursue their dreams and passions. They have to do the stuff that “really” matters. This is the advice that young people get all the time: hunker down and devote yourself to what you really care about (in the grand, abstract sense).
The main problem, of course, is that young people often don’t know what they like until they’ve had a chance to try it. Watching legal dramas isn’t enough to tell you whether you’ll actually enjoy being a lawyer.
But having fun means you get to try things out. Even if you don’t have an abiding passion for something, turning it into a game or a fun experience can be enriching.
I don’t have a deep, burning, existential desire to crunch spread sheets. But I have fun with them at work. I’ve learned more from having fun with them than by sitting down and studying them seriously.
Get out there and play!
