You have not addressed something in your post, but maybe is is obvious : why do you want or need to become an expert ? You can have a very fulfilling life being a jack-of-all-trade. In a fast moving word, I am not sure I would like to become a world expert in a shrinking domain. I would say the vast majority of humain beings, both dead and alive, are no expert. So is this because you have an insatiable curiosity ?(but I don't think that being an expert is necessary the best to quench your thirst for knowledge) Do you want to stand out in a crowd ? To have a legacy ? I am also kind of frustrated knowing that my time is limited, and it reduces somehow my options, but I have come to term with the fact that I won't be able to do "everything" during my time on Earth.
