more mature to want to focus on this life? wh?

Spiritually speaking it can be considered desirable to process the emotional baggage of our past until it no longer holds us back, and we are able to focus on our present self, and future self improvement.

I don’t mean that focusing on your kinself is ‘immature’ in terms of mental development, rather that being focused on it means you’re still emotionally/spiritually processing the past.
