Same here for myself really. Although I don't have quite so much free time. I used to also be very shitty and lazy after work each day (well, I still am) but I found doing a sport helped that. Sports are easiest to get into, and often you might find a friend who will go with you and increase your motivation. Its hard to motivate myself to do something I've found, which sucks big time. I guess I'll just learn everything about being a mod over time haha, we'll see how it goes.
