"Open" is one of the most under-appreciated words in the English language. If I was going to start a religion it would be called "Openism." The church would have a great big flashing neon sign that would always be on and the door would always be open. "Open" is almost always associated with good things - open source, open learning, open-minded, it's a long list. And for me, it's constant challenge to try to be more open to people and ideas and things I may not like. I like to see signs that say "OPEN" because they remind me to relax and open up to what's around me.
