This book is superb and very well balanced between his limits. And this is so because although being based in Wall Street and other USA stock markets, is fully understandable in Spain and I suppose everywhere, a quality another good books lack as these many from the UK, with his excessive focalization in the City and must of all, the doubtable Sterling Pound, a mental barrier. Of course, nobody can avoid some themes are more difficult than others, but simply these are so: work, study and life. This book explains better than any other I know including some in Spanish.
