Personally I don't believe in fortune because it implies luck. That there is some force is acting on a persons behalf. Let's just say you can act to put the odds better in your favor.
I am not saying that anyone can be an astrophysicist or a rocket scientist, but if they put forth the effort they can reach goals they never thought they could.
History is filled with unlikely success stories.
Richard Branson: At school he was an academic failure, and left without any qualifications. Now he is an entrepreneur and businessman, who founded the Virgin group of more than 400 companies.
Samuel Walton: Growing up in the great depression of the 1930s, Walton had to milk family cow and do numerous odd jobs to help family survive. By the time of his death in 1992 he amassing a fortune of over $23 billion with his Walmart chain of stores.
Being fortunate means different things to different people. Not everyone can be an astrophysicist, but not everyone wants to.
Obviously not everyone can be successful and happy. Look at retards. They cant do anything no matter how hard they try. Then there are rocket scientists that can build rockets. People like to think that if your not retarded you can do anything which is moronic. There is a scale from one to ten when it comes to potential and to put us on this scale you would use every number. Just like there are fat people skinny people and everything inbetween or smart people dumb people and everything inbetween. So too is there people with max potential and some with no potential and everything inbetween. Only idiots cant see it. Its ignorant to talk to someone who has half your intelligence and motivation etc. and tell them they can do what you have done. You dont know that! You dont even know whether or not we are in control of our actions. Free will is not a fact its a theory. And its beliefs like this that brought on the saying nothing is as it seems.
