If you think you can do it, you can.

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

Quality is not an act, it is a habit.

Never complain and never explain.

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

Be gentle to all and stern with yourself.

I can, therefore I am.

Do not weep do not wax indignant. Understand.

Without hard work, nothing grows but weeds.
