The credit is yours, regardless of whether or not you accept it. The concept of deserved credit, however, should not factor into one's sense of worth as it relates to successes or failures during life. You, as an individual, performed as your biology and mental state (arrived at through prior experiences) dictated, but here's the hard truth; those two qualities are a part of the individual and can't be separated from him or her when judging worth, which negates the entire reason for the concept. The author of this thread seemed to conceive of himself as a disembodied third party, examining himself from a position without the influence of biology or mental states, but the truth of the matter is inescapable; those qualities are essential to who you are; they are you.

"I did nothing to earn my talents- they are extension of things I was either born with or acquired during my upbringing, namely intelligence, stubbornness, pragmatism, idealism, a complete disregard for a good night's sleep, etc. I didn't choose to be good at math."

His talents, things he was born with or acquired, what he didn't choose. He is what the world has made, and in some small way, the world is what he will make. The man that typed the original message, filtherton, will endure what befalls him merely through his continued existence, and deservedness is only what others will apply to him along his journey. He is free to act as he wills, knowing that what he wills is the result of his biology and mental states, and that effectively is him. He is not the result of those factors, those factors are his essence as a being.

The failure to accept one's whole self is a fatal oversight of philosophers throughout history, and it gained traction through the belief in an immaterial soul or its equivalent that is independent of human thought or experience. For whatever reason, folks still cling to it, as though in a fugue; it is difficult to accept that past experience and biology aren't somehow foreign causes involuntarily forced upon the 'pure' and independent individual. Free will is an unfortunate casualty; everyone is free, they just aren't accepting certain parts of themselves that contribute to decisions, pushing away instead of embracing the factors that shaped them, that are them, namely biology and past experience.

Edit: The whole dilemma reminds me of a dog chasing its tail. He could pause for a moment and realize that the tail is actually a part of him, but he only resolves the truth after managing to capture the furry thing. Unfortunately for us, our identity isn't a physical object to be captured with our teeth, so we're endlessly performing mental 360 degree rotations in search of the elusive and supposedly free will. The tail is our body and mind, biology and past experience, and the current mental state resulting in the upcoming decision that we're fretting over (is it or isn't it free?); it is the summation of our existence as a distinct individual.
