If you've worked in sales then you know people who try to take the easy way out by not preparing as much as they should for a call, by leaning on their personal relationships more than their ability or by not putting in the time it takes to develop their skills.
Being good at sales is hard work. It's not just using a formula that you plug in. I believe we create our own luck by being over prepared, knowing our product and service, and learning and understanding what our customers really need.
But I have to confess - sometimes I'd rather be lucky than good!
