Some people are smart because they push on in the face of great opposition. Others win plaudits for "knowing when to quit" and changing direction. It's all a bit wishy washy, Its not that its wishy washy, its that one of the great keys to success is knowing the difference between the two. On the one hand, if you are on the right track you probably need to be ready to persevere in the face of enormous opposition, but if you are on the wrong track, no matter how far you have gone, change directions. Telling the difference can be quite challenging though, at least in some cases.
