It's called financial planning but it all has more to do with luck and timing. The best financial plan is to spend less than you make. Easy to do when you make enough money. We have continuously had strong gains in production and business is doing great after the bank bailouts that inversely have the people of the world crippled. Wages for workers have not kept up with inflation or the price of goods and service. The very reason we have the tRUMP effect or people struggling in contrast to a strong economy for the lucky people like you and me, unaffected.  
The idea that you're selling; "how easy it is", is really insulting with intent, but I am not sure what you get out it. Do you?
My father-in-law was that way, always selling this story about how much money we could make in stocks. I lost half my wealth because I was that way, he lost all his and died pennilessly. He was a retired commercial airline piolet. Captain bigshot. Republican character in the likes of tRUMP.
