Is he more successful than you?
===============================
I think that we can say that Soros is more economically successful than Sirs, because (a) he is older and has had more time to amass a fortune and (b) damned near everyone is less financially successful than George Soros.
Of course, success should not be measured in terms of dollars exclusively. Perhaps Sirs derives more satisfaction from one of his patients surviving that Soros derives from making a killing on exchanging kroner, schillings and zlotys.
Having heard an interview with Soros a while ago, I can say that Soros is a vastly more optimistic fellow than Sirs, who relishes finding fault with pretty much any opinions other than his own and those rather few with whom he agrees.
My experience has been that being optimistic is always a boon to one's endeavors, whatever they are. Many of my students are slothful unimaginative schlubs, but I still manage to teach rather a lot more Spanish to them than someone else might, because I treat them like intelligent and productive beings.
With regard to investments, I set goals in my mind for how low a fund would have to go before I sell it, and how high it might rise before it has become too risky. I follow these and above all, the advice of my excellent newsletter, and most years, I make more money by investing my retirement funds than I do actually working. This is silly and unfair, but it would be insane to not take advantage of opportunities that the system affords me, because I decided long ago that the system is weird and I cannot change it even slightly. So I take my losses and refuse to mope over them and always expect the best.
Still, I feel more successful as a professor than as an investor, becaue I put a lot more energy into being a good professor.
