I reached the same conclusion but in a roundabout way. I think the ultimate goal is to know about one's own self at the most deepest of levels. One way obviously is engaging with the self at a deeper level which is not always possible. Unfortunately, it is extremely hard to master.

However watching others and just collecting more datapoints help in the process of learning. You are learning to read and be more observant regardless of judgements.

I found the article really good.
