Didn't you ever see that Star Trek episode where Picard goes back in time, decides to NOT get into a bar fight that nearly killed him and instead of becoming Capt he ends up being like 3rd rate science officer? The lessons he learned from that near death experience helped mold him into the type of person that could be a Capt.
I liked the overall lesson of that episode, but I didn't like the episode itself so much. I guess TNG was just too preachy for me.
