One thing I have learnt from all these great men is that one can be very lucky or talented at making money, but unfortunately don't have that money management skill. Alot of people don't know that being able to manage the money you earn and multiplying it to produce more money is a skill on its own. It's too bad that this great men only lived for the present and never made good plans for the future.
Maybe some did make plans for the future by borrowing to fund their investments, then the unfortunate tragedy struck them. Being rich means having high income/purchasing power, it does not mean financial security/freedom. Proper planning and financial discipline can bring about generational wealth.
I have seen individuals with big pays and yet had nothing just because they did not have a clue on how to handle their earnings. Earning money and retaining money are two totally different artworks and majority of the people concentrate on the former. It is financial discipline that actually makes the difference whether in the short term wealth or long term stability. I also believe that what is actually freeing the people is the act of knowing how to invest wisely and live within one means since having money and not having control of it is purely an illusion of feeling rich.
Fame can indeed be deceptive. With all the fan love and support, one would think the money would still be coming in forever. Well some like Michael Jackson have the privilege of getting that steady revenue even in death.
Thank God for technological advancement, those who are really smart can actually make sure money doesn't stop flowing in for them. Like in the music industry now, musicians can still get paid till eternity as long as their songs are being streamed. It will be rare this present generation, getting these kinds of reports that once famous and rich people died poor and remained forgotten for ever.
