1. Jot 'Em Down
This step is somewhat a must. However, if you consider yourself a super computer robot, you can skip number one and get down to number two...you're still reading so you don't think that you're a mega mind. That's good because it's never great to be too confident with yourself.
Number one is writing them all down. It never hurts to write all of the things you need to do. Write them in a small notebook, a tickler or something, or jot them down in a piece of paper and post it on your refrigerator door or on your own bulletin if you have one. And don't forget to write when you need to do or accomplish these things or in other words, your deadlines.
