I like to throw away a fair chunk of change right off the bat on a bunch of Adwords campaigns. The intention is not really so much to make a profit, but rather to weed out the thousands of non-converting keywords and tweak my landers/funnel for high conversion rates.
Most of the clients I work with know what a hawk I am about chasing those wrong-headed, short keywords. It's a bad mindset most of the time - the time to give up on those keywords is often before you even start.
