Got a kid who plays endless hours of video games? Me, too. Have them read this article... and check it out yourself. It's a thoughtful piece written by someone who clearly knows a lot about video games... and life. He points out that life is a game of managing your resources - the most important of which is time.
You spend your time with the choices you make. Here's the thing. Your internal state (health, energy, and willpower) determines the quality of those choices. You're likely to make poor decisions when you're tired or not feeling well. The things I talk about in this blog (exercise, diet, sleep, stress) are all practices for improving your internal state... keeping it high so that you are in a good position to make the larger choices - what you do for work, where you live, the people you let into your life.
The writer points out the symmetries between how life starts and ends. "At the start of the game, you had no control over who you were or your environment. By the end of the game that becomes true again. Your past decisions drastically shape where you end up - whether you're happy, healthy, and fulfilled... or not. In your final days there is far less you can do about it. That's why your strategy is important. Because by the time most of us have figured life out, we’ve used up too much of the best parts. Now, you'd best get playing."
