Another one is setting up a business that he does not know how to manage, he spends millions on this business venture but eventually folds up, and he loses all his fortune because of mismanagement.
One of the worst thing to have ever tried was venturing into a business he has no idea about.... Decision making is also a thing; how do invest in a business with knowing the prerequisites on how to maximize profits? You could employ labour, Yes... Without a doubt, but how do you get to know where there's shortage?
Another winner is he entrusted his winnings to his relatives to claim because he did not know how to read and write and had no valid ID; he only got 20% of his total winnings because his relatives told him because of a deduction in the form of taxes.
"Ignorance is bliss, but illiteracy is mindlessness".. in whatever you do, always try to get yourself tutored. Nothing beats the fact that you know a thing to yourself, without needing possible aids to run them.
Having a Do-do list is important!
