I finally figured out what was missing from my life. A specific extra curricular activity, martial arts. :)
I recently started MMA (Muay Thai and Brazilian Jiu Jitsu) and couldn't be happier. It's been about 6 weeks and I've already lost weight and feel amazing! So much fun! As a kid (from 9-16) I did Tae Kwon Do and very briefly, some Brazilian Jiu Jitsu at around age 11 for about 6 months so martial arts isn't completely new to me. However, I've had an almost 10 year hiatus but things are starting to come back.
