Compromise

Do it on the unimportant stuff.  That's easy.  If you care less then they do, then cave.  And the more  stuff you can put on the "unimportant" list, the better off you'll be.

Never do it on the important stuff.  The core, the essentials, the things that matter most.  Be passionate, be persuasive, and be firm.  Notice I didn't say stubborn.  Or impossible.  But when it matters, when the soul of the idea is at stake, don't cave.  Especially to win something on the unimportant list.

Now here's the hard part.  What belongs on which list? (*Hint- there's probably too much on the "important" list after the first draft)
