"No one has ever failed in sales. Some people just stop trying."
It reminded me that success in sales (as in life) comes by doing the same things over and over again, and always learning from your mistakes, so you can do it a little better the next time. Every successful person I know has struggled numerous times and made countless mistakes. The reason they are successful today, is they never gave up.
The biggest mistake you can make...
Is To Quit Trying!
