I get a basic feel for people right away. I'll know if they'll make it or not. I know if they'll be trouble makers or not. And I'm seldom wrong, but its something I've always been able to do when meeting new people.

Right now, we have two newbies at work.
~One started right before Christmas. I knew he'd fit in well, become the top seller, and create trouble with our trouble maker. He's done just that.
~The other started a month ago. I liked her but had no thought of her performing well. I still think she's a wonderful woman... but oh-my-gawd.... she can't get even the most basic concept down.
