I think that's a big help in living each moment, to remember that, this is it, this is the day. If I don't do "it" now...I may never have the chance to do "it" later.
Oh, believe me, I didn't always think like this. I used to think, ah, I'll do it later. One day. Some day. Soon.
Now I think-- do it NOW! It needs to be done! Don't procrastinate any more. How precious time is to me now. Well, I've always appreciated it, but always thought I had millions of tomorrows.
Hey, do it now.
This is the day.
