I was a commission-based salesperson once. Not door-to-door, but my job was to push for sales. And I was terrible at it, I just couldn't do it. I hate pushing people into things. As a result the customers and my co-workers (who saw a chance to leech off of me for commission) walked all over me. It was one of the worst jobs I've ever had, and I was so relieved to get out of there. The only reason I had it in the first place was because I'd been unemployed for a while and I was desperate.

I feel like you have to be really cutthroat to be a good salesperson, and I am not.
