The neuroscience stuff doesn't add much new from a practical standpoint, but some people (including myself) like to know that these changes have a real, biological effect - and perhaps aren't just imaginary.

I think you know what is referred to when I say "negative emotion" (emotional states we tend to find unpleasant or want to avoid - fear, sadness, guilt, etc.) I understand that all emotions serve a function, but rough distinctions likes "positive" and "negative" still mean something for most people, so I like to talk within those terms.

The reward for sites like Reddit maybe entertainment, or information, or just coping with boredom.

That is so awesome to hear - thanks for sharing and I'm glad to hear it helped your friend.

You don't spend money AT ALL? I have a hard time believing you. :)

Drug lords and the black market only exist due to government prohibition. Watch what happened in the 1920s...there are no more alcohol-related mobs, why is that? Because the free trade of alcohol became publicly acceptable. You didn't have to trade beer behind closed doors anymore, you could just go to the stores.

Opportunity cost is definitely an important concept for anyone to learn. The concept of buyer's remorse is based on perceived opportunity costs.

What you believe is what you think about what you perceive. :)

The way I see it is: All thoughts are based on concepts, which are based on perceived patterns.

Awesome, I love reddit! Thanks.

I think that's the most reasonable approach to take these days. Taking kids out of traditional school completely can be really daunting. I believe as long as parents play an active and critical role in a child's education outside of schools, they should turn out fine.
