Satisfaction and interest both are two different words but both are related to each other . A person does anything when he or she founds interest that thing unless he or she won’t even think about it and once a person feels satisfied he/she won’t do that thing again and they won’t found anything interesting in that thing so then they need to find another thing in which they have interest if they won’t found anything interesting they will do nothing . For example a man marries a woman and few years later he feels bore living with her . I wrote above quote in context that a boy gets breakup from his girl and in start of his breakup he enjoys that sad feelings but after sudden time he get used too to that breakup phase, sad feelings and then he feels satisfied from that feeling and now he don’t found anything interesting with that sad feeling.
