Another great thing is you can usually find someone who is up to have fun, even if you have no social connections in a place you're travelling to. I was visiting Barcelona a few years ago and emailed the misc- alias seeing if anyone wanted to visit Montserrat with me, and 5 of us went up there and had a great day together. Best part is, it is usually cool people who say "yes" - the abject nerds aren't going to respond to that kind of email.
Nope, not even close to true in my experience. Almost all of the high performers I know have a huge social network they can tap into and you can't finger them as SWEs from a mile away.
Well, that's how I feel about some of my coworkers. I know it is a strong word, and I think it is appropriate. For the most part, they're not bad people, but they just have an extremely limited outlook on life(from my perspective).
