Yes it did. I own my own business and it was all thanks to having no fear going door to door, and business to business talking to people. All those years my parents forced me to go out in service made me unafraid of talking people into buying computer services.
Hell if you can sell someone the Watchtower you can sell just about anything!! In fact I have more success selling computer services than I ever did getting people interested in the Watchtower.
