You're making sense:)
I could then argue, wisdom, non-wisdom... Lost Soul / Found Soul no punt intended sort of:)
That being, maybe those who are happy within themselves, know who they are, accept people for who they are, don't judge, are mature, hold some wisdom of life, have learnt alot in life, regardless of their passion are happy to let people be themselves, believe in what they want to, it's their life.
Those, who are lost, haven't found themselves, haven't learnt much about life, just live day to day, and therefore their belief is something they hold onto, maybe all they hold onto, try to force that to others so that there is a commonality, someone they can relate to, in this otherwise, maybe, lost, lonely world of theirs...
IDK without asking them:) Just a thought.
