Never complain and never explain.
Wherever you are - be all there.
The dog that trots about finds a bone.
What you do today can improve all your tomorrows.
You never know what motivates you.
Without hard work, nothing grows but weeds.
If you're going through hell, keep going.
Be gentle to all and stern with yourself.
Be kind whenever possible. It is always possible.
The most effective way to do it, is to do it.
