It would be very amusing to have a book, if it has not already been written, about the financial adventures of intellectuals over the last few centuries, as we often find them very curious in many biographies. It is fascinating to note that the most common type of intellectual, and above all the genius, is absolutely incapable of a prudent, moderate, intelligent financial life. We often see them in difficulties for long periods, most of the time, if not generated, made much worse by themselves; normally, the state they experience is one of dependence, at the mercy of fortune. There are great heirs, and more numerous ones who have piled up debts, loans and extravagances that only absolute irresponsibility or unjustifiable optimism or complete stupidity could allow. But very few are satisfied with a modest life, paid for by their own efforts, in line with their possibilities and, above all, one that improves as time goes on due to sensible behavior and not a sudden stroke of luck. It is certainly impressive.
