You never know what motivates you.
It's always too early to quit.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
To know oneself, one should assert oneself.
Either you run the day or the day runs you.
Well done is better than well said.
Be gentle to all and stern with yourself.
I can, therefore I am.
If you can dream it, you can do it.
A discipline I have observed is an attitude of love and reverence to people.
