Well worth the time spent

Ryan is an excellent teacher. It's as if he is sitting in the chair next to you as you pair-program. You get to hear how he thinks and derives a technique, so not only do you learn the right way to do things, but also how he got there (so hopefully you'll remember the next time you have to solve a Rails problem).
