The biggest thing for me has been my own attitude. As a former college scholarship football player I spent years stuck in the attitude that every ride has to be faster than the last ride. The past couple years I've been able to change my outlook and have different rides on different days. Some days I work on my spinning...some on climbing, some riding with my gf and some on riding my TT. The variation and the lack of self-imposed pressure has made riding so much better.
