We may have all sorts of experiences, insights, thoughts, and maps, but we don’t really know.
Since this is a secret of sorts, and many adults don’t admit to or don’t speak openly about it, it easy for us as kids to think that adults must know.
I don’t know and (I assume) they do.
And when we still don’t know as adults, some of us keep that belief.
I don’t know and someone else must.
Of course, this may be true in a limited sense. Some will have more experience and insights into certain areas of life than I do, and I can learn from those people. But it’s not true in any final sense.
We are all just winging it.
