Losing Listings ...

You lost the listing to a cheap fee.
You lost it to an overvaluer.
You did not lose it forever — but you acted like you did.
Yet, because you didn't nurture them every week when they were with competition, you made the vendor feel they had to admit you were right and they were wrong to come back second time round
So they picked someone else instead.
You handed them away.
That's your fault
