I am glad nobody mentioned his name. Maybe because he is so popular that everybody knows the reason behind his success, still, I find a complete justification to list his name.This man, as everybody knows, is Warren Buffett.Before continuing my answer on the reasons for his most outrageous way becoming rich, consider these facts first.He started investing into stocks from the age of 11. By the time Buffett was 15, he had a net worth of about $6,000. Now, at the age of 86, his wealth is $73.3 Billion. All his money came from his investments. He is not an entrepreneur or a co-founder. He earned money from his investing tactics.Until the age of 53, his net worth was around $620 Million, from 53–86, his net worth increased to $73.3 Billion. A whopping 72,680,000,000$ margin, earned in a span of 33 years. He joined the billionaires list at the age of 56.With his investments, many people who have believed in him benefitted by being a shareholder for his company “Berkshire Hathaway.” Berkshire Hathaway was able to generate 20% APR for its share holders every year? No other company has achieved this feat for so long.Why do I choose Warren Buffett:Warren Buffett is not a co-founder to any company like other Billionaires (like Jeff Bezos, Mark Zuckerberg etc.). He is an investor. None of the other rich people were so successful as Buffett is. Everybody has a flaw behind their success (like, an argument that Mark Zuckerberg copying the idea of Facebook from his friend), but I find Buffett clean. He has failures, but he is clean of any allegations.His business tactics to become rich. It’s no less than outrageous. He knows every nook and corner of investing. He is so confident in his investments that he was not a Billionaire until the age of 56. All his trees bore fruits later. He planted a tree and nurtured with his genius mind. He know the results of his investments beforehand.The genius mind behind his investing tactics. It’s a pure mind game. I can quote below example for his genius strategy. Back in the days when there were many cola brands, Coke was one of the major one. There is a reason Buffett chose to invest in Coke leaving the other drinks behind. He “predicted” Coke is going to be a fast selling global drink. He is a part of success behind it. Here is the reason.There are taste buds in our tongue that recognizes a particular flavor. Like sweet, sour salt etc. When such taste hits the surface of tongue, the receptors sends a signal to brain, that this food or drink tastes like sweet/sour etc. This is captured by our brain and it memorizes it.Ex: When you drink an orange flavored soda, your brain recognizes its tanginess and sends a signal, which the brain memorizes. If you try drink it again, say an hour later, brain avoids having it, since it is fresh in memory. When you drink Coke, the brain couldn’t decode the flavor. Hence it cannot memorize. Its indistinguishable. In short, there is no taste memory to Cola in brain. What’s the advantage? You cannot get used to it. Every time you drink Coke, its refreshing. If you drink Fanta or any orange flavored soda, your brain recognizes the flavor and since it got accumulated to it, it tends to avoid drinking. But its not the case with Coke. You can drink coke anytime of the day or with any meal and still find it refreshing. You can try this yourself.The genius mind recognized it pretty quickly, a reason he chose Coke over all other flavored sodas to invest. People got to drink something, so it will be a long term investment. Now, it is the time to increase sales and root the drink dearer to people. What’s the best way to make it reach more to the general public? Then he thought of this brilliant idea. Associate Coke to all the moments of happiness so that in a customer’s conscious mind, they should think of Coke when they are happy or when they are having Coke, they should think of happy moments. All the advertisements associated to Coke are always showing a festive, light hearted happy moments (like Christmas ads, Diwali festive in India’s Coke ads, Confessing and accepting love etc.) which shows happy moments in a person’s life.The color of Coke is Red and white which interprets happiness (as in Christmas lights), the tagline is “Open happiness,” all associating to moments where a person is happy. So, whenever a person see a Coke in the market, they gets it as it is associated to some of his happy moments earlier. Once you hooked up to drinking Coke, the sugar and refreshing taste does the rest for you.Like this, he increased the sales of Coke to many folds. And later Coke gained a rapid global market becoming the most drinking soda by the world. And this is just one of the examples of his investing and marketing techniques.All his other investments has a theory and shows his brilliant mind at work. And to say the least, he is the least alleged or corrupt person in the list of Billionaires.Those are my few reasons to say Buffett was outrageous in the way he got rich.Update: Below is the video, in which Buffett speaks on some of his investments tactics and answers many other questions. Do watch it if you are interested. The above example on Coke is one of the examples he discussed briefly in this video.
