Know or listen to those who know.
The wise does at once what the fool does at last.
Without hard work, nothing grows but weeds.
I can, therefore I am.
It's always too early to quit.
After a storm comes a calm.
Be kind whenever possible. It is always possible.
Begin to be now what you will be hereafter.
Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
Be able to be alone. Lose not the advantage of solitude, and the society of thyself.
