Positive <==> Successful?

Went to an IndyHall happy hour tonight at National Mechanics. It was excellent.

There's one thing I've been noticing over the past couple weeks. "Successful" people are positive. I know this is nothing new or terribly original, but it's something that, when you really get to talking to people, you can't help but notice. They have a way of seeing the lesson and the value in almost any experience.

I have only anecdotal evidence yet (I'm a scientist), but I think it may be true that positive people are "successful" too. I'm thinking this is because there are fewer opportunities for outright failure when the majority of experiences have some value. So positive people are less likely to classify what other people would as outright failure; they're just stepping stones—educational moments—on the way to something else.

Ok, that's enough Tony Robbins for tonight.

By the way, I don't really hate marketing. I just have a lot to learn.
