Jim Carey gave a commencement speech that went viral a couple years ago, he said the same thing most successful people say (deeply paraphrased here): You have to work really hard and go for it. However, working hard is a necessary condition but it's not a sufficient condition. For every Jim Carey there are countless failed comedians who worked just as hard. I'm not saying he doesn't deserve it, but we labor under the delusion that the free market always rewards hard work and if you don't reach your goals it's because you didn't work hard enough. Of course you can't reach hard goals without working hard, but working hard doesn't always get you there. You can do everything right and still not catch a break.
