Be gentle to all and stern with yourself.
If you're going through hell, keep going.
Leap, and the net will appear.
To know oneself, one should assert oneself.
Expect problems and eat them for breakfast.
If you think you can do it, you can.
If you've got a talent, protect it.
Quality is not an act, it is a habit.
Go for it now. The future is promised to no one.
Either you run the day or the day runs you.
The answer to old age is to keep one's mind busy and to go on with one's life as if it were interminable. I always admired Chekhov for building a new house when he was dying of tuberculosis.
