One of the things that happens to all of us is getting rooted in a static perspective. It is sometimes difficult to see this calcification from our own viewpoint, but it can stand out like a sore thumb to other people. The trick seems to be working furiously to keep our defensive reactions from browbeating other people out of telling us when we seem wrong from their perspective. That, and finding enough people who do the same to keep the input useful.

Long story short: we can all be wrong due to errors in data and thinking. I suppose the best indicator is being slightly uncomfortable at all times from a constant awareness of this. Comfort seems to presage motionlessness unless it is the comfort of temporary respite from hard work with the sure knowledge that shortly it will begin again.


More later.
