Know or listen to those who know.

By failing to prepare, you are preparing to fail.

Be gentle to all and stern with yourself.

Without hard work, nothing grows but weeds.

Begin to be now what you will be hereafter.

It's always too early to quit.

Quality is not an act, it is a habit.

If you're going through hell, keep going.

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