"Ability and necessity dwell near each other."
Many people will suffer for years in a miserable job, habit or relationship, until things get so bad that they can't take it anymore. This is why it's easier to divorce a monster than a fairly decent person, and why so many people lose weight when their health is obviously falling apart. On a scale from one to ten, if our physical, emotional, psychological and spiritual needs are met -- even at a one level -- it is much harder to find the motivation to create positive change than if even one true need drops down to zero. Everyone deals with life circumstances that are less than ideal. People who are happy simply refuse to dwell at a low level of fulfillment; they take action long before misery sets in.
