To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
The most effective way to do it, is to do it.
What you do today can improve all your tomorrows.
Begin to be now what you will be hereafter.
The secret of getting ahead is getting started.
Never complain and never explain.
Well done is better than well said.
Go for it now. The future is promised to no one.
Be kind whenever possible. It is always possible.
Never stand between a dog and the hydrant.
