That's it? My commute is easily 1.5hour+ daily, each way. Most of the mechanics I work with started out working on their own bikes and reading stuff like Sutherlands/barnetts/internet. Then cut their teeth under more experienced guys under the shop. If you get familiar with properly adjusting most of the basic bike stuff and know how to use bike related/specific tools than that will really help. It's much easier to train someone when you don't have to explain how a QR hub is properly adjusted or what a say cone wrench does.
