The question to ask is: “Are there considerations other than enjoyment to recommend English literature over business?” (and possibly also: do these considerations outweigh being richer?)
Gandhi would not want to take a pill that made him want to kill people, even if he could then enjoy life more by killing people. This is because not killing people matters to Gandhi for more reasons than just because it matters to him.
However, if it is in fact easy to self-modify to enjoy something, that’s a good reason not to make serious decisions on the basis of what you’d enjoy doing most.
