Did you ever do any podcasts that covers the probability and numbers game aspect of cold calling and sales? Was listening to one of your podcast episodes and seems to be a lot of similarities between trend following and cold calling.
Lots of small losses (the people who say no) and then the big gainers (the companies who say yes and become great customers).
Discipline, having and following a system, managing your bankroll (which in sales is time), cutting your losses (move on to the next call), letting your winners run (developing a long standing client who does a lot of business with you, tracking and analyzing metrics (best days to call, best times to call, best approach to use, best questioning strategies, etc).
Know any good write-ups on cold calling and math?
