were full of super sweaty entire days and weeks of constant door to door rejection in the brutally hot brazillian sun, but I looked back on those days with fondness as a door to door salesman because at least I had a companion to suffer with and also it didn't really matter if everyone rejected us because we were getting credit in heaven for trying our best. Whereas with sales there is no heavenly motivation, its all about making the sale or making zero dollars for all your hard work. Go a few days or even weeks without a single sale and you get to watch the psychological breakdown of some pretty resilient guys and gals.
