While I can't think of an actual change of direction, I enjoy the mental gymnastics of being challenged. It sometimes reinforces my thoughts, sometimes makes me figure out why I believe a certain way, and makes me succinctly communicate ideas, so that others may understand quickly.

Changing positions on a topic in a flip-flop way indicates a lack of independant thought (as does continuing to yell the same things over and over). Some weak-minded people simply agree with whoever they talked to last.

An intelligent person's thoughts usually evolve. Core values rarely change, but when approched with an open mind, many topics are grounds for proper discussion, and an evolution towards clear thinking.

Of course, some people are so open-minded, their brain leaked out.
