On being willing to stand alone and be different.
Excellent Howard Marks quote:
"The question is not, do you dare to be great? The question is, do you dare to be different? To diverge from the pack is required if you're going to be a superior in anything. Number two, do you dare to be wrong? Number three, do you dare to look wrong? Because even things which are going to be right in the long run, maybe look wrong in the short run. So you have to be willing to live with all those three different things, different, wrong, and looking wrong, in order to be able to take the risk required and engage in the idiosyncratic behavior required for success."
