Can I - a normal salary man - become a millionaire or billionaire? Yes, of course. Then people go to buy lottery tickets. Is there any other way except but the light-striking-probability lottery? I don't think so. There are many kinds of 'lotteries' around us. They are special because they will come to us even though we don't buy the tickets. You can be a star over a night or the price of the stocks you bought can be 100 times of it. It's not that rare if you invest your money in cryptocurrencies. You may think that these are all as rare as you being struck by lighting. But my point is that there are many lightnings in the sky. In order to get the lightning, we have to keep two things in our minds. These are mindset and execution. I will tell more about these two things later.
