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

You never know what motivates you.

If you're going through hell, keep going.

Without hard work, nothing grows but weeds.

Do not weep do not wax indignant. Understand.

Quality is not an act, it is a habit.

Problems are not stop signs, they are guidelines.

Always desire to learn something useful.

Be gentle to all and stern with yourself.
