You never know what motivates you.
It's always too early to quit.
The wise does at once what the fool does at last.
Leap, and the net will appear.
Be thine own palace, or the world's thy jail.
Only the educated are free.
Without hard work, nothing grows but weeds.
The dog that trots about finds a bone.
Be kind whenever possible. It is always possible.
Wherever you are - be all there.
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.
