There would be 3 broad sets that your discussions would fall in: Beliefs that you both mutually agree on, Beliefs that you are able to convince your past-self through reason and Beliefs which make the past-self regard your future-self as being actively stupid for holding.

That (re)definition makes Shalmanese’s third law tautological rather than clearly false. That’s fine, so long as no attempt is made to draw any conclusions about, well, actual advanced wisdom.
Does more advanced wisdom look like bullshit than bullshit looks like advanced wisdom? I doubt it. Bullshit is selected for appearances.
