If you're going through hell, keep going.

Either you run the day or the day runs you.

What you do today can improve all your tomorrows.

Things do not happen. Things are made to happen.

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

Quality is not an act, it is a habit.

Know or listen to those who know.

Without hard work, nothing grows but weeds.

It's always too early to quit.
