If you think you can do it, you can.
If you're going through hell, keep going.
Be gentle to all and stern with yourself.
The wise does at once what the fool does at last.
What you do today can improve all your tomorrows.
Problems are not stop signs, they are guidelines.
Who seeks shall find.
Either you run the day or the day runs you.
To know oneself, one should assert oneself.
If you've got a talent, protect it.
The whole business of marshaling one's energies becomes more and more important as one grows older.
