I keep a weekly to-do list. But one of the most important items on that list is the word "Relax".
For a very long time, I concentrated on how much I could do: improving my skills, creating work for clients, trying to build a successful business.
For the most part, this worked out well for me, but it meant I was working around the clock. I would spend 8+ hours working for my day job, and then immediately follow it up with side projects until obscene hours of the night.
What this resulted in was some absolutely undeniably amazing work, but I would be a walking zombie most hours of the day. My personal life suffered, my health suffered, and then my work suffered.
So one day, it finally dawned on me that this was not the way to live my life. I had heard rumors that there actually was more to the world than a computer screen, and I set out to find out what that was.
I rediscovered hiking and camping. Along with my wife (and sometimes our dog), I've explored caves, waterfalls, glaciers, volcanos, and these tall green things called "trees." I've watched meteor showers, stared down mountain goats, and even once spent an entire 24 hour period without thinking about work.
The weirdest part? I'm actually more productive in the long run. Taking a few days here and there to actually enjoy life makes a world of difference.
Hiking isn't for everyone, but find your thing and go do it.
