Play off everyone against each other so that you have more avenues of action open to you.
Once you consent to some concession, you can never cancel it and put things back the way they are.

A million dollars isn't what it used to be.
We don't have a monopoly. Anyone who wants to dig a well without a Hughes bit can always use a pick and shovel.
