When is the last time you did something so fun that you didn't want to stop, even to pee?
For me, it was about 6 minutes ago. I just got clip-less peddles for my mountain bike. Even though it goes against logic, clip-less peddles are when you clip your shoes onto your peddle. This allows you to pull up on the peddle, as well as the typical pushing down. I've been off my bike for about a week now, because I got the wrong shoes and have been beaten down by some seasonal allergies. Everyday, though, I've dreamed about riding my bike. Excitement isn't as forceful as when I was a child, so I've let life get in the way of getting the right shoes, but today I got them. I got out of the car, immediately put my shoes on, and started trying out my new bike technique. I just couldn't wait! I couldn't go inside to put my belongings away or pee. Excitement took over and had me on the bike, attaching and detaching. Only being able to ride around in a tiny circle on a drive way, since I don't really know how to work the mechanics, I felt 4-years-old again. I practiced until I was about to wet myself.
Now, get out there and find something so fun that you almost pee in your pants. Life's too short to not be having that much fun.
