It's always too early to quit.

To be a good loser is to learn how to win.

Begin to be now what you will be hereafter.

If you're going through hell, keep going.

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

Go for it now. The future is promised to no one.

Always desire to learn something useful.

Quality is not an act, it is a habit.
