Give it up, Richard. What you post here and on other threads has no
relation to anything. You are debating exclusively the chimeras
of your imagination, your mind here is like a hall of mirrors, full
of endless reflections of self-made nonsense.

Exactly. You are running in circles constantly and nothing for
you makes sense in this domain. That's fine. Not everyone has to
be a physicist. I am not a virtuoso pianist and I can live with
that awareness extremely comfortably and well.

No, it's you.

Notice I didn't say "the problem is you" because it's not a problem
to have no talent for something in particular. The only time it becomes
an emotional problem is when a person somehow falls into the trap of
convincing oneself that it's absolutely essential to "work with" the
domain one cannot possibly succeed in..
