To know oneself, one should assert oneself.

Either you run the day or the day runs you.

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

What you do today can improve all your tomorrows.

Quality is not an act, it is a habit.

It's always too early to quit.

Begin to be now what you will be hereafter.

Never complain and never explain.

Be kind whenever possible. It is always possible.
