I only study the things I like; I apply my mind only to matters that interest me. They'll be useful-or useless-to me or to others in due course, I'll be given-or not given-the opportunity of benefiting from what I've learned. In any case, I'll have enjoyed the inestimable advantage of doing things I like doing and following my own inclinations.
