Can people really change, or do they simply modify their behavior to suit certain situations?

I believe change is motivated by drive and humility and respect and if somebody does not have that, they cannot change themselves. Either circumstances would change them or blessings would change them or people would change them.

Some people can actually change and learn but some people can't. People who have personality disorders usually won't change ever. They're not wired to even want to change.

Why... I don't know, but I've got a feeling that you want to forgive someone for what they did in the past even though you can't summon up enough courage to do so.

I don't think I have changed much, but I have been chastised about things and changed my behavior.

How is modifying your behavior to suit the situation not changing?
