Those resources won't really help you to learn much! Do something that requires an attention span! I have started reading SICP when I have a free hour to goof off. I also have it bookmarked on my phone.<p><a href="http://mitpress.mit.edu/sicp/full-text/book/book-Z-H-4.html" rel="nofollow">http://mitpress.mit.edu/sicp/full-text/book/book-Z-H-4.html</a><p>I recently switched from coffee to green tea, and I am amazed at how much more information I can absorb, because my attention span is longer. I actually think it's analogous to the NFL, where rookies aren't any good until "the game slows down for them", well live has slowed down for me!
