Re: No more Mr. Scott
The other strategy, which I've used often to success -- overpromise, but then deliver fully on that overpromise.
Coming from a working-class Italian background, the work ethic I grew up with was always: "Yes, I can do that." And then busting your butt to figure out how to do it, and doing it -- even if you have no idea what you're doing it at first.
Granted, this isn't ALWAYS the best strategy (it all comes down to ROI, after all -- no use in going above and beyond for something that's not going to be worth it), but if you really push yourself, you can do amazing things -- and impress others and yourself at the same time.
