In her beautiful book, One Thousand Gifts, Ann Voskamp relates one pastor's answer to the question, "what is your greatest regret?"
Being in a hurry. Getting to the next thing without fully entering the thing in front of me. I cannot think of a single advantage I've ever gained by being in a hurry. But a thousand broken and missed things, tens of thousands, lie in the wake of all the rushing. . . Through all that haste I thought I was making up time. It turns out I was throwing it away.
(Quoted from Mark Buchanan's Restoring Your Soul by Restoring Your Sabbath.)
