If you're feeling overwhelmed by tasks, take a look at how long they'll take. Then, follow the two-minute rule from legendary time-management expert David Allen's book, Getting Things Done: "When a task takes less than two minutes, don't schedule it; don't set it aside for later; don't set a reminder--just take care of it now. Then it's done."

Besides: Don't you have enough on your schedule already? Sometimes, "just do it" is the best way to clear your task list.
