Things do not happen. Things are made to happen.

What you do today can improve all your tomorrows.

It's always too early to quit.

Quality is not an act, it is a habit.

Be gentle to all and stern with yourself.

Never complain and never explain.

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

Either you run the day or the day runs you.

If you're going through hell, keep going.
