I keep a set of hardcover notebooks. When I start a new book, my notes always begin on the third page. The first two pages are my table of contents. When ever I take note of something that might be important later, I add it to the table of contents for easy reference. I've actually tried many different software applications, but I've found that when I write something down, I'm forced to think about it a bit, and I remember/learn better. With software, its too easy to just copy, paste, and forget. I'm also a very visual learner. My notebooks are full of diagrams, pictures, arrows and other text annotations. I've yet to find a piece of software that easily lets me do that.
