Lynda.com might be the best $25 a month you ever spend. Lynda is basically a series of very well thought out tutorials for how to do just about anything on almost all of the major software platforms. You want to get better at photoshop or learn photography or teach yourself CSS? Lynda has hours of video to help you sharpen your skills. They also have an iPhone app that streams all of the content to wherever you are. So instead of your normal commute nap to work, you can learn how to apply a mask in illustrator cs5. Fair warning, these are videos about software... so if you're in a warm room and didn't get a full night's sleep, they may put you to sleep.
