WRITE THINGS DOWN!!!

I really should write things down more often, and right when I think about them. Take this assignment I am doing for Overflow at the moment. I have an idea and I should have written it weeks ago. But here I am dilly dallying and then all of the sudden my creativity decides to go on auto pilot and now I don't remember how I wanted my assignment to be. I should just write things down right away so when my mind decides to go on a rampage I can still be productive.
