What part soever you take upon you, play that as well as you can and make the best of it.

If a man is to live, he must be all alive, body, soul, mind, heart, spirit.

Try to be happy in this present moment, and put not off being so to a time to come--as though that time should be of another make from this which has already come and is ours.

Time will always exist but you will not. Stop your mind from drifting off into the future if you aren't there yet. Cherish the seconds of your life, live now not tomorrow. -Enlightened-

Well, it does make you realize that life, even at its longest, is still very short.

Why always "not yet"?  Do flowers in spring say "not yet"?
