Martin Luther King Jr's constructive use time

Can't find it right now, but one of my friends posted an old video, an interview with Martin Luther King, Jr, one of America's greatest leaders of all time. That post reminded me of MLKs "Letter from Birmingham Jail."

You've heard of it, no doubt. But if you've never actually read it, do so now. It will stay with you and inform the rest of your life. As you read, remind yourself he's in jail at the time, writing in long hand. No cut and past to craft the words. No internet or even (gasp) books to look up references. Just his mind. And time. Time he used constructively.

One part that impressed me is his response to the plea to wait before taking further direct action:

"Such an attitude stems from a tragic misconception of time, from the strangely irrational notion that there is something in the very flow of time that will inevitably cure all ills. Actually, time itself is neutral; it can be used either destructively or constructively."

Time itself is neither friend nor foe. It's what you do with it that makes all the difference.
