Does Being Grumpy Pay?

Grumpy people.

Ugh.

We all have at least one in our workplace that tries to bring the whole place down. Some days it's easy to ignore them, but we all know, we can't always hide from them.

Until I read this article, I always believed that grumpy people hated what they were doing, but that's not necessarily true.

Researchers say that grumpy people are better at their jobs than you are because they concentrate on one task when positive people tend to enjoy a wider variety, thus making them a jack-of-all-trades and being way to distracted.

So, is this article saying grumpy paves the way to success? Maybe I should change my ways?!
