As everyone else has pointed out, as an active young person, the amount you're riding isn't challenging your fitness enough to do anything. Riding more often (even if you stick to short rides) will get more miles into your legs, and it sounds like you're not yet acquainted with the endorphin rush that comes from riding really hard. I won't tell you how to ride, but let's just say that leisurely riding doesn't do it for me anymore. Good luck.
