To know oneself, one should assert oneself.
Without hard work, nothing grows but weeds.
The dog that trots about finds a bone.
Wherever you are - be all there.
Problems are not stop signs, they are guidelines.
If you can dream it, you can do it.
Well done is better than well said.
Be kind whenever possible. It is always possible.
Leap, and the net will appear.
If you think you can do it, you can.
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.
