The thing about taking up something new is that it is hard at first, and then reaps you some kind of reward for your perseverence. My two newest endeavors (that I practice on alot) are playing the baritone uke (and Momma's guitar!) and frisbee golf. I somehow fit these in with climbing trees, riding the mountain bike, etc... and it makes me feel cheated every time the lights go off and I have to sleep.
There isn't enough time in a day anymore...
I've got musician's callouses on my left hand fingertips and the coolest thing is I can talk about a minor chord configuration while having a beer where I couldn't before. New hobbies open up whole new conversations.
Which is cool because old conversations get... well... old.
So take up something new and get passionate about it.
It's pretty cool.
