Without hard work, nothing grows but weeds.
Only the educated are free.
It's always too early to quit.
You never know what motivates you.
What you do today can improve all your tomorrows.
Wherever you are - be all there.
If you're going through hell, keep going.
The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
The most effective way to do it, is to do it.
I'm the son of an everyman. My father is a teacher. He teaches physics at a boys' school in Sydney.
