This is a massive over simplication, but my personal take is that the people who make it big always had a nag that they were going to be successful.

Success doesn't strike me as something that you just stumble upon. There is always work to be done, but most people just won't do it. I'm not saying most people are lazy, I just think that they decide to work on the wrong things.

Furthermore, if your determination can be deterred by an article, I wouldn't bet for you to be successful to begin with.
