if you can't figure out how a vast, organized dues-paying professional guild full of highly educated, intelligent, like-minded individuals can help you, i kindly suggest that you contemplate the possibilities a while before trying your hand at being a c-level executive because you'll probably be caught in the same position as the o.p.

a professional board is basically a labor union dressed up for white collar people. they'll argue until the end of the earth that they aren't, but let's be real, that's what it is.

also, if you're a vp-level or above, and not a significant owner, negotiate a severence package. ever wonder why they have severence packages? this is why. because if you don't, you're highly likely to become a bitch. in fact it's pretty much guaranteed because the cost of losing you is nothing.
