The most important pressure your prospect must feel from you is that you are making sense about why he should buy.
He should be thinking “ man you are right.” That kind of pressure is a nudge. Frequent nudges in the form of test closes.
He should not be feeling any other pressure from you where it is felling like a push. That is when you become billed as a high pressure sales person.
And, if you did manage to sign the person up, buyers remorse and regret and cancellation of services or product or premiums is more likely to happen.
