In college, my roommate was taking classes learning Freehand and Illustrator. Each version release would leapfrog the other product. Being industrious, I did all of my roommate's assignments on my own, and I learned the apps on his tuition. I didn't do his work for him. I just did it to learn. I was only able to do this because of a.b.m.a. I still use that knowledge from his classes on a daily basis.
