Every now and then you will encounter a potential customer that doesn’t like you or your product or both.
Maybe its your colour. Maybe its your voice. Maybe its your religion. Maybe its just random.
It doesn’t matter why he doesn’t like you, it only matters that you quickly realise you’re wasting time.
Your time and energy is valuable. Invest it in customer’s that like you.
If he’s made up his mind that you’re an ass, so be it.
That’s his problem. It only becomes your problem if you try to change his mind.
You can’t please someone against their will.
