"Sometimes I don't even stop to give people autographs, because if I were to do that, I'd never get where I'm going..." ~ Jay -Z
Like I said in one of my notes before, the world is suffering from a chronic case of attention deficit disorder -- this age of mass advertising, instant gratification and advanced communication technology (cell phones, e-mail, text messaging, etc.) has brought us to a place where inattentiveness and the inability to focus is the norm, and since we live in a constant state of information overload, we're actually conditioned to live in a constant state distraction, interruption and inattentiveness.
So one of the major keys to raising your productivity is to stop allowing yourself to be distracted. If you have something to do, stop letting random, trivial interruptions prevent you from doing it, because not only will that take you off track and disturb your train of thought, it'll also take you longer to establish the flow you were in before you were disturbed. Even further, not only will you not get things done in a reasonable period of time, but (if you take a second to look at the big picture) you'll actually be sustaining a habit that leaves you incapable of accomplishing the important tasks you need to create the life that you want.
