If a person changes in a way that gradually makes her/him be in peace with the inside and outside world, I'd say it's a right change. And if someone tells me s/he has not changed and feels good, is deeply satisfied and has a peaceful life, I'd say perhaps there has not been any kind of flaw that would make that person's life miserable so, no pain/no change.
Most of the people who are not truly feeling sparkles of joy in their hearts, I believe, are those who are fit in none of the above categories most of the time. They insist on what they think, say, believe and had been get used to since years ago. They are ready to point their fingers at whomever they think is eligible enough to take most of the responsibilities of that gloomy atmosphere. Parents, societies, spouses, relatives and friends are easy targets for that matter. They can be indeed to blame but at the end of the day it's us that can take the control of standing still, to move on and modify and well, this is not of those easy modifications. It requires a great commitment and cleverness.
