You chose it - as part of your self appointed goal. It's logical to assume you choice was not random but the result of your judgement of its value.
Do you honestly believe that? Our choices can be reflexive, random, judgmental or "just because." Do you think it's possible it's not really my goal, but curiosity?
Your post is pretty much mind-reading like I noticed with some other posters here. My choice does not have to be my "self-appointed goal," (such as retirement, getting married, children, etc.), but a mere diverison of curiosity, so it's not logical to assume anything about my or anyone else's thought processes.
Maybe this maind-reading streak is just characteristic of a particular crowd of poeple who, by their own admission, live by and subject everythng to a priori assumptions without realizing how wrong that can be.
