I'm having the opposite problem...I'm not motivated to do anything but ride. The only way I can make myself work is to ride there, then I'm chomping at the bit for the ride home. My gym membership is a total waste. I have no desire to clean, see friends, go away. All I want to do is ride (and eat and sleep).

So, I'll send you a little of my motivation. Be warned, it won't make you any faster, or ride longer distances. It will just make you think about nothing but riding.

Really though, I think your issue is the heat.
