Never complain and never explain.
If you're going through hell, keep going.
Expect problems and eat them for breakfast.
To know oneself, one should assert oneself.
Always desire to learn something useful.
Begin to be now what you will be hereafter.
Go for it now. The future is promised to no one.
It's always too early to quit.
The dog that trots about finds a bone.
Problems are not stop signs, they are guidelines.
The greatness of a man's power is the measure of his surrender.
