The secret of getting ahead is getting started.
Without hard work, nothing grows but weeds.
You never know what motivates you.
Begin to be now what you will be hereafter.
Never complain and never explain.
To be a good loser is to learn how to win.
To know oneself, one should assert oneself.
Wherever you are - be all there.
Leap, and the net will appear.
The wise does at once what the fool does at last.
I travel all over the country making speeches for people I believe in.
Teaching was the hardest work I had ever done, and it remains the hardest work I have done to date.
