If you've got a talent, protect it.
To know oneself, one should assert oneself.
Never complain and never explain.
Without hard work, nothing grows but weeds.
Quality is not an act, it is a habit.
Know or listen to those who know.
Begin to be now what you will be hereafter.
I can, therefore I am.
It's always too early to quit.
Be kind whenever possible. It is always possible.
Success breeds success, and failure leads to a sort of fallow period.
