A very successful salesperson once told me that a key ingredient to making more sales is to always agree with your prospect.

“As soon as you go against the other guy,” he told me, “or make him wrong, though you may have been 100% right — you’ve lost the sale. And a salesperson’s job is to make the sale, not to lose it, and not to be “right””

He challenged me to a 30-day “agreement challenge” that’s simple to understand: In all my conversations over a 30-day period, only agree with people. If you catch yourself disagreeing with someone even once, start again at Day 1. He told me that most people couldn’t even make it through the first 24 hours before failing.

I’m starting mine over, again, today.
