Guessing that you will remain who you currently are is probably the maximum likelihood guess. You probably are more satisfied with who you currently are than with any of the other possible "yous" that you might envision. That's why you choose to be who you are. (You might not like your station, but that involves things outside of your locus of control.) Therefore, there is not a different, preferred "you" that is trivial to imagine. This makes predicting that you will remain the same seem, to me, to be a good guess.
