First off, hempnbass, props on an awesome post.

What have I learned?

Thing aren't always as they seem.

Rationality has its limits.

Sometimes knowing yourself and being yourself are mutually exclusive.

Mundane activities while sober can be very boring. (Note: I disagree with others above. Pot doesn't make everything seem boring; it just makes not being high seem boring. Fun activities are still fun; they're just a lot more fun while high.)

I am not the only person in the world.

We are not the only species in the world.

Things can make sense without having order.

Whatever you think reality is, it's not.

There are a lot of tragically misguided people out there.

Nowhere is spelled, "now here."
