Life is fragile. We're not guaranteed a tomorrow so give it everything you've got.

We have to know that nothing is promised, nothing is guaranteed, especially tomorrow.

Sometimes you just give everything you have, and you do your absolute best, and it doesn't stack up.

The worst thing in the world that can happen to you if you're an engineer that has given his life to something is for someone to rip it off and put their name to it.

Do a little good today, don't wait until tomorrow or the next tomorrow, for they are not guaranteed to you nor me

You want to be the pebble in the pond that creates the ripple for change.
