I dread jumping on calls with people I don't know, especially when they don't convert. Spending an hour on a call just for it to go nowhere drains me. I'd much rather only speak with people who already understand the offer and are ready to make a decision. For those further along than me, what changed the game? Was it adding more friction to your funnel, asking better qualifying questions, nurturing leads with content before the call, or is this just part of building a business that everyone has to push through?
