It's never easy giving out advice, whether it's asked for or unsolicited. Either way, chances are good that they won't actually take it, even after you've spent at least an hour reciting your best sales pitches. They'll listen, then they'll frown, shake their head and recite a long, drawn-out list of reasons why they can't possibly do what you're suggesting. Every now and then, however, you get lucky. Give them at least five minutes before you decide to call it quits.
