Be gentle to all and stern with yourself.
Without hard work, nothing grows but weeds.
What you do today can improve all your tomorrows.
If you're going through hell, keep going.
Begin to be now what you will be hereafter.
Things do not happen. Things are made to happen.
Either you run the day or the day runs you.
Always desire to learn something useful.
Leap, and the net will appear.
To know oneself, one should assert oneself.
The food that enters the mind must be watched as closely as the food that enters the body.
