How do you be a good door to door salesman?

The key to being a good(GREAT) door to door salesman is actually very simple.... Just Do It!!! To try is to fail... when we try something and we don't succeed immediately, we say "oh well, I tried...gotta find something else now.." If we Just Do It, and we fail, we do it again until we get it right.... It is all about attitude and your work ethic... If you quit on yourself, you will lose everytime... EVERYTIME!!!
