And when are you supposed to do it? During office hours when you should be working on your regular job, or after 6pm when no business will be open for your sales call?
Yeah, during the day. Work from home and sneak in an hour or two here.
Building a company requires an incredible amount of hustle, if you can't figure out how to sneak in a couple of hours here and there to talk to people/pitch, sorry but that indicates a total lack of hustle.
