To know oneself, one should assert oneself.

Quality is not an act, it is a habit.

Be gentle to all and stern with yourself.

It's always too early to quit.

Begin to be now what you will be hereafter.

Do not weep do not wax indignant. Understand.

If you think you can do it, you can.

Know or listen to those who know.

Without hard work, nothing grows but weeds.
