two approaches

People are often convinced, for a while, by strong opinions; or at least a little scared by them which leads to respect, of a kind.

You could spend time honing your opinions, making them increasingly impressive and deadly when deployed in conversation...

or you could spend time getting rid of permanent opinions and look instead at what is really going on.

Of course, since being opinionated is still fun you could at parties still voice the strongest of opinions, maybe about things you have an opposite view about.
