Joseph Taylor Posted over 3 years ago Can we "engineer" our own interests through repeated exposure? I took it by the title, to relate to the psychological field, for example reciting a mantra to change behaviors, which are a result of perhaps negative events in a persons life, the most significant event is being born, where and when, and all of them have their implications for the future. When you start following a vocation, that would be a mix of chances, your past experiences, and the choices that you make. Teachers are important for guidance - as equally is the pupils temperament, everyone is different, some with a chip on their shoulder some seem to glide through life without a problem. I would say to your question, the big events ARE more important than the small, but the fable says the tortoise beats the hare.
