If you don't pay appropriate attention to what has your attention, it will take more of your attention than it deserves.
You can fool everyone else, but you can't fool your own mind.
Use your mind to think about things, rather than think of them. You want to be adding value as you think about projects and people, not simply reminding yourself they exist.
Anything that causes you to overreact or underreact can control you, and often does.
