To know what you think, write it down. Forcing myself to write something down, to structure it, to let it see light is the best way for me to clarify what I actually think about something.

Secondly, by sticking it out there magic happens. People either reinforce your idea, modify it, disagree with it or just take it in and mull it over. All of these are worthwhile. Just being seen to know things and be thoughtful about your work is good for your career. But beyond this your ideas get tested, they get expanded, you can adapt. This is a powerfully evolutionary idea. We get to test and improve our thinking in real time.
So, this is why I blog.
