Another Lucius Seneca quote:
No one persuit can be successfully followed by a man who is preoccupied with many things
What are the things that you are preoccupied with? How many things do you have on the todo list in your head? How many of them have you gotten done lately? If you're like me then you have a big list floating around your head where things drop on and off of the mental checklist and you never really get to most of the things on there. Write it down! Use a text document on your computer, send yourself an email, start a google document, or even good ol' pen and paper. Just get it out of your head so you can focus on things one at a time without worrying that you're going to forget something.
