Try the difficult task of making a human class. Have attributes be dependant on different things such as parent's characteristics and randomness. Then based on the 'makeup' of the person write a synopsis guessing what the human will end up accomplishing in life.
i.e A person with high intelligence, a medium amount of self esteem and a low temper will probably succeed moderately in life, but not as much as capable because his/her temper is always getting in the way
Something like that
