The lesson I got from looking at all these influential people is you can be exceptional in your field but if you do not know how to manage your money you might just die penniless. I personally do not want to pass away after suffering from poverty. I want my last days to be spent in bliss.
Well, it's all about financial management skills. The wise people said that earning money might not be as difficult as it is to manage that money, because your money will run out very shortly if you don't manage it properly, even if it's a lot. We often hear stories of people making so much money from gambling or from a lottery, but then they either lose it all back to gambling or spend it on things that don't last very long, and eventually, they get back to square 1 again, which doesn't make any sense.
When you have money, you should know how you should use it so that your future stays secure at least. If you can't make it enough for your next generations to have, it should at least allow you to live a good life without any financial problems, but that can only be possible if someone doesn't just buy materialistic things or gamble with the money, but make investments and start businesses with it.
Nothing is that difficult in this world, it's just that you should have enough sense to understand what's right and what's wrong.
