Suggestions on time-fillers

Hi all -- just as the title states, I'm looking for time-fillers that are good for self-betterment. The upside to my situation is that I'm young, making bank, and live within five minutes of work, so my commute is essentially non-existent. The down? Well, there's not much to do in my area. It's all business-y, so younger kids like myself (23 by the way) aren't around much.

I play soccer in a rec league with the high schoolers and adults who still play. It's fun, great workout, etc. That's MWF. All other days, I'm in the gym. Another downside is that the only gym in the area is a Planet Fitness, but I'm making that work.

Even after gym/soccer, there's still two or three hours that I spend watching TV or playing video games. I'm exhausted physically, but feel like I can be doing something to make me sharper.

I've limited my TV watching to the Science Channel and Comedy Central, and limited my gaming to Rocksmith, trying to pick the guitar back up.

Any other suggestions? Before someone suggests reading, I really can't get into it. Not unless it's an article about something I enjoy. I've been debating getting my pilot's license, taking some aggressive driving courses, vocal training, but none of that is local, more of a weekend thing.
