Can you sell salt water to the people aboard an ocean liner or ice to an eskimo?
Or would you struggle to sell an order of fries at a fast food restaurant?
Me personally, I don’t sell. If someone wants what I have to offer, great! If not, who cares? I’m not placing my value (or salary!) on whether or not a person wants what I have to offer.
Also, what do you think of salespeople in general? Do you find them slimy or are you excited at the prospect of something new and exciting to buy? I personally don’t like being sold to. It’s annoying.
