Never, never, never take the first no. There are a certain number of people in business, industry, and government who always say no the first time you suggest something new, because they're lazy... But there's another group... who always say no the first time... because they want to see if you believe in it enough to come back and ask again. So never take the first no. Always go back and ask again. As a matter of fact, I take about four no's and then I figure out how to get around the guy, but that technique comes with age.
