You can procrastinate away your entire life with "someday I'll surely take advantages of all the free resources on X that are out there and finally learn X and maybe even shift careers!"

Just think of all the things you never bother to learn despite having a latent interest even though you can open a new Youtube.com tab right now and fire away. It's hard to start, and then it's overwhelming when you do, and then you feel like a failure when you don't stick with it.

Isn't it worth quite a lot to snap out of it and finally do it? It doesn't surprise me that people find this to be worth thousands of dollars. When you consider how fatally expensive it is to procrastinate your goals forever, maybe these schools are a bargain.
