If you think you can do it, you can.
Wherever you are - be all there.
The dog that trots about finds a bone.
Go for it now. The future is promised to no one.
Never complain and never explain.
If you're going through hell, keep going.
Be gentle to all and stern with yourself.
What you do today can improve all your tomorrows.
It's always too early to quit.
Without hard work, nothing grows but weeds.
When I was younger I probably didn't understand something basic about tact, but I think it kept faint-hearted people at arm's distance and that's not such a bad thing, because life is short and I know the kind of people I want to work with.
