I read with interest in which I note one mentioned that anything which becomes an obligation starts to look like work. I totally agree with such view. During the course of FIRE, one will be happy when he/she gets to do things which he/she like. Sometimes, when one starts to feel obligated to do the interested activities, it becomes like a work which is not fun anymore. I feel that this is the way in which one must cast aside all the obligations and make decisions in accordance of his/her desires.
