A few years ago, I felt like I was stuck in a rut, so I decided to follow in the footsteps of the great American philosopher, Morgan Spurlock, and try something new for 30 days. The idea is actually pretty simple. Think about something you've always wanted to add to your life and try it for the next 30 days. It turns out, 30 days is just about the right amount of time to add a new habit or subtract a habit -- like watching the news -- from your life. There's a few things that I learned while doing these 30-day challenges. The first was, instead of the months flying by, forgotten, the time was much more memorable. This was part of a challenge I did to take a picture everyday for a month. And I remember exactly where I was and what I was doing that day. I also noticed that as I started to do more and harder 30-day challenges, my self-confidence grew. I went from desk-dwelling computer nerd to the kind of guy who bikes to work -- for fun. Even last year, I ended up hiking up Mt. Kilimanjaro, the highest mountain in Africa. I would never have been that adventurous before I started my 30-day challenges.
