Scared

What are you afraid of? Some of the most damaging fear isn't physical. It's mental. You had that great idea and didn't do anything with it, then six months later you see what you thought of on the internet. You get the worst sinking feeling, and wonder how well the guy who did it is doing.

It wasn't always like this, though. There used to be things that were very smart to be afraid of, as that gigantopithecus in the dark inside that cave would probably rip you to pieces. So, fear was a valuable survival tool back then. Not anymore.
