If you think you can do it, you can.
Quality is not an act, it is a habit.
To know oneself, one should assert oneself.
If you can dream it, you can do it.
It's always too early to quit.
Either you run the day or the day runs you.
Wherever you are - be all there.
The wise does at once what the fool does at last.
Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
I remember things that happened sixty years ago, but if you ask me where I left my car keys five minutes ago, that's sometimes a problem.
