To what extent is one responsible for how accomplished one can be in life? Many
John Stuart Mill was a childhood prodigy, as you say, but in later adolescence he suffered a "nervous breakdown" (probably depression) which he thought was caused by too much intellectual work as a child. So, at the same age you are now, he was not very functional. He also died when he was 67--not a long life by today's measures. There are many routes to academic accomplishments; perhaps hard work is the only thing they have in common, and you know that you are capable of that. In any case, you cannot change the past or guarantee the future--only work with the present. If you enjoy academics and aspire to greatness, I wish you the best of luck!
