Remember, I'm the guy who broke a fender trying to take a wheel off. I'm klutzy and not mechanically inclined at all. I DO want to get better at working on the bike, and I was pleasantly surprised to find I seem to have managed to clean and lube the chain correctly, at least according to the owner of the bike shop. I am going to figure out how to handle minor truing adjustments, darn it, I'm going to need to.
I still feel like I'd do better with a teacher than trying to learn something by reading a book - I wouldn't even mind reading the book if I had a teacher to "check my work." It's a work in progress, as is everything in life. Something I think will prove to be quite helpful is the sheer amount of bike repair videos on YouTube. I will look into a bicycle repair book more, but I'm petrified it'll be written in a foreign language for someone like me who isn't mechanically inclined at all.
