you can only change your attitude to things, you can't change how good you are at Pokémon, just your attitude to getting better at it. so technically you can't change anything
If something you do results in something about you changing, then you've changed it, no?
I guess I just don't quite get how "you can't change anything" is the natural result of whatever you're thinking, unless you're trying to be profound through oversimplification.
