Some suggestions for you :
Better be a nettle in the side of your friend than his echo.
In the words of a great writer, we find our own neglected thoughts.
It is one light which beams out of a thousand stars. It is one soul which animates all men.
Every man supposes himself not to be fully understood or appreciated.
He who has put forth his total strength in fit actions, has the richest return of wisdom.
The best lightning rod for your protection is your own spine.
