To know oneself, one should assert oneself.
Things do not happen. Things are made to happen.
It's always too early to quit.
The dog that trots about finds a bone.
If you're going through hell, keep going.
Begin to be now what you will be hereafter.
Either you run the day or the day runs you.
Problems are not stop signs, they are guidelines.
Be kind whenever possible. It is always possible.
Be gentle to all and stern with yourself.
As I've said many times, the single most oppressed class in America right now is the teenager.
