What you're describing is what Nassim Taleb calls "tawkers." People like economists, journalists, pundits, etc. who talk big but don't have any skin in the game for being wrong or irrelevant (time is a great example). Since there is no feedback loop to punish bad or irrelevant takes, they can continue tawking for a long time.

When I have similarly strong opinions, I do act on it because I enjoy seeing how right or wrong I was. Markets are a harsh, expensive teacher. You either learn a trick or two about uncertainty, overconfidence, humility, etc, or you run out of money.

I think you're better at it than you're letting on even if you decided to not play. You already understand the properties of the game.
