Things do not happen. Things are made to happen.
To know oneself, one should assert oneself.
Wherever you are - be all there.
If you're going through hell, keep going.
What you do today can improve all your tomorrows.
Be gentle to all and stern with yourself.
It's always too early to quit.
Either you run the day or the day runs you.
You never know what motivates you.
Begin to be now what you will be hereafter.
Thought is the original source of all wealth, all success, all material gain, all great discoveries and inventions, and of all achievement.
Do not trust to the cheering, for those persons would shout as much if you and I were going to be hanged.
