My approach to selling all boils down to this:
“Hi, human. I sell this thing (in my case writing) for a living because I believe in it. It’s benefited myself and others you may know. Are you the right person to pitch? If no, do you know someone who is? If yes, is now a good time?”
I’ve been writing full time for 10 years now. Much of that time, if not half of the time, is spent asking people if I can write for them. In that sense, I’m either a writer who knows how to sell, or a seller who knows how to write.
Either way, I’ve followed the above pitch for the last decade. I don’t know if it’s the best sales approach, but it’s worked alright for me, and it’s one I feel is the most respectful.
Know a better way?
