A comprehensive list:
Hacking Knowledge: 77 Ways to Learn Faster, Deeper, and Better | OEDb
I haven't read the whole list so I may be just repeating. In any case, here are my suggestions:
1) I suggest doing a lot of reading. I highly recommend getting a delicious account (you can check out what I'm reading at
ArthurHung's bookmarks on del.icio.us. It's a bookmark efficiency site. I pretty much just keep adding to my network of those who I estimate are smart from the bookmarks that they have, and add them to my network. So far my success with this site has been nothing but phenomenal. I check my networks everyday for my daily reading material instead of the newspaper. I might not be explaining this site in enough detail, but if you're interested, click my link and find out for yourself.
2) Socialize with people who are very smart, preferably smarter and more enlightened than you in some way. If everybody had a Steve or Erin Pavlina as a close friend, I'm willing to bet that prisons would shut down, no one would cheat and we would have solved world peace.
3) I suggest teaching others what you know, those that want to learn, of things that you do or understand really well. There are many times where people think they know something perfectly and that they can learn nothing more; when teaching others they may learn many great things for themselves. I've experienced this many times in my life.
4) Use your dreams, don't talk about them. From my favorite book, the WarOfArt by Steven Pressfield, he writes about how you shouldn't talk about your dreams that help you figure things out. I agree with this, I think you should just listen to your unconscious and let it tell you the best information it can; it will usually be superior to some offhand third rate comment a friend or associate can give you which can actually screw up or lessen the help that your dream was meant to give you.
5) Randomly browse Wikipedia, starting from a subject you like. Wikipedia is getting better and better, since the standards appear to have been raised over the years. Also, since it's now harder for people to join, there are a much higher level of socially conscious smart people who post there. You can through nearly random clicking learn about 50 topics within 2 hours. From these 50 topics, you are probably going to find at least 1 thing that you can truly appreciate to have learned.
6) Holistic learning:
