It's always too early to quit.

Be gentle to all and stern with yourself.

Quality is not an act, it is a habit.

Without hard work, nothing grows but weeds.

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

Always desire to learn something useful.

If you're going through hell, keep going.

The wise does at once what the fool does at last.

The most effective way to do it, is to do it.
