Never do anything yourself that others can do for you.

Never trouble another for what you can do yourself

I often say to my assistants, "Never trust anybody," but what I mean is that you should never trust someone else to do a job exactly the way you would want it done.

Never do things others can do and will do, if there are things others cannot do or will not do.

You cannot help people permanently by doing for them, what they could and should do for themselves.

Don’t ever work for someone you don’t want to become.

Never do yourself, what you can con professionals into doing for you.

I don't think you can do anything for anyone without giving up something of your own.

To others never do
That which yourselves would wish undone to you.

To others never do
That which yourselves would wish undone to you.

What you do not want done to yourself, do not do to others.

NEVER HIRE ANYONE to do a job until you’ve tried to do it yourself first.

Don't do unto others what you don't want done unto you.

What you don´t want done to yourself, do not do to others.
