Happened to me as well. But you have to realize there are so many things are going on you might not be aware of eg. relations, background, even luck! Instead, try to exploit your recognition of their success and ask/learn about their story. That will help you a lot too. When you think that way: they went through a path instead of you so you can now explore their story and get their experience much faster. And don't forget: when there are 10 competitors with virtually the same skills and performance its still only one who wins the contest with the prize and goes away with all the chicks. The others seem to be unsuccessful from a bird view, but in reality there might be not much difference in value. Realizing this made calm, I am totally ok with lottery. Everything is a lottery a bit, except you really nail it: but that requires so much work I won't ever be envy.
