I have a similar problem. It's really hard to work 8 - 10 hours then come home and try to have the steam to dive into a mathematics or algorithms textbook and go through it in a way that really lets me internalize the material.

Could be that I just haven't found the right books or rhythm for this kind of learning, though. Doesn't help that I'm a pretty disorganized person with my time outside of work, heh.

I've read a few posts on this blog before, and remember enjoying them. I'll have to read a few more. I think it's partly because of how much I hated formal education, and partly because a blog doesn't have the same physical presence as a textbook, but blog posts are less psychologically draining to think about than a book, for me.
