Review, review and review some more, that's what my best teachers used to tell me in school. The reason I say they were the best is because I just remembered how important it is to review things. For example, your lecture notes and material you have already covered; and not just once or twice, but several times until the information becomes burned into your memory.
I mention this because I just read over some of my posts and said to myself, "you can write better than that." I know that because I have done better than that in the past. What it takes is practice, an effort to improve, and lots of review to help determine progress and improvement. OK, so I should be writing better than I have been.
What's kind of wierd is that it's 4:40 AM and I am sitting here typing and thinking about this stuff. I should be in bed sleeping. I'm going to bed.
