It is certainly true that productively developing a valuable skill set will set you apart from the vast majority. With a few helpful insights, the right attitude, and an ability to quickly overcome obstacles, you will be an exceptional person, without a doubt. If you assign credit for success to a person's attitude and perseverance, then certainly "luck" had little to do with it. Where things get dicey is when you ask the next set of "whys". I.e., "why does this person have such a helpful attitude? why do they have such perseverance?". To what do we attribute these qualities? If it's genes, then it's luck (you can't take credit for your genes). If it's parenting, then it's luck (you can't take credit for your parenting). Perhaps it's neither genes, nor parenting, but instead "spirit" or "will". So, whence these qualities? The person's "soul"? Something immaterial? Anyone who provides these kinds of answers is necessarily endorsing brain-mind dualism, which (near as anyone can tell) is almost surely false. Does this mean that everyone can disclaim personal responsibility for their actions? Surely not. Choosing to believe in one's own agency in turn empowers one's own agency. But everyone's believing in a fiction, no matter how necessary or adaptive this fiction happens to be, doesn't render it true.
