Things do not happen. Things are made to happen.
Either you run the day or the day runs you.
Begin to be now what you will be hereafter.
Expect problems and eat them for breakfast.
Only the educated are free.
You never know what motivates you.
The wise does at once what the fool does at last.
Go for it now. The future is promised to no one.
If you've got a talent, protect it.
Be kind whenever possible. It is always possible.
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.
