Susan is famous now (for good reason!), but before she was famous, she wrote this excellent blog post: If Susan Can Learn Physics, So Can You — Susan Fowler.
I came across it because I was trying to learn physics again. (I started off taking physics ages ago but dropped it because, well, long story, but I ended up in Computer Science and Mathematics and went on to have a career at IBM so it worked out.) I followed a lot of Susan’s advice, and while I am not good at physics yet, I highly recommend this to anyone serious about it. (Just stay away from programs that want to weed out most of the class because they want small class sizes.)
