Your average close rate was never about your scripts.
You can't handle the "think about it" objection because you yourself overthink.
You can't handle the fear objection because you have your own fear and anxiety.
You can't handle giving me until tomorrow because you yourself procrastinate.
That's why your close rate is average.
How many more deals will you have to lose before you see that it's your bad karma and mental blocks that needs handling?
How many more thousands will you spend on sales training before you fess up?
