Yes, it's true. There are tons of people out there who are characterized by vapid, mindless optimism.

Yes, they are annoying. They are a turn-off. They don't actually accomplish much.

But it's a massive mistake to correlate their optimism with their vacuous mindsets. Negativity also has the capacity to be mindless. And it my experience, it often is.

Don't be overly negative in an attempt to appear smart. Usually, it has the opposite effect. And it makes you miserable in the process.
