Witness your thoughts. Your thoughts are attachments.
It's very hard to grow, because it's difficult to let go of the models of ourselves in which we've invested so heavily.
A moment comes when "other" is no longer other.

You have all the time in the world, but don't waste a moment.
Faith is what is left after all your beliefs have been blown to hell.
