I also like the idea that blogging is an opportunity to organize your thoughts.
Much of life passes us by unless we are paying attention. The writing helps focus where we might skip over for something shinier.
Next thing you know you have a kite hobby, or you've opened a kite shop. And then you run into someone you knew in high school, and they're like, "Weren't you going to be a psychologist?"
One day perhaps I will be a blogger and someone will say "Weren't you in tech and owned a business?" and I can reply, - Yes, still am ;D
