I thought like you once then I realized that you can learn from reaching. I give a lot of advice on here and trying to articulate my thoughts to others really helps me understand my own thoughts. Sonetimes in the midst of just trying to explain my opinion to another person I have a burst of insight. And because I'm learning things on my own instead of simply being told it sticks longer. Since I've been using GAG my social skills have went from pretty good to spectacular. Sometimes the value of something isn't as straightforward and obvious as we think.
I don't usually ask questions, but I think answering helps me too. It means that I actually think about things and how I feel about situations and I like that I get to know more about myself and my beliefs by being asked to think about them :)
