Show how you have changed your mind on something, anything, that you never thought you would.
Here are a few of 
1.  Trump.   I think he is a terrible person...  except for war.  I believe he is anti-war, and I could be convinced to vote for him on that basis alone.
2.  Tucker Carlson.  What a nut job, so I thought.  He really has some interesting and intelligent thoughts, especially in his twitter videos,
3.  Man buns...   They don't bother me anymore, I have just come to accept them.
4.  Pepsi vs Coke.   I was always Pepsi.   Now I am neither. 
5.  Bill Gates.  I thought the guy pissed perfume and shit potpurri.  I have learned he is a megalomaniac, and not kind to humanity.
