So say you successfully make a change to one or more personality traits - I'd expect self esteem to go down, stress to go up and all the negativity experienced to happen. Changing personality isn't like putting on prescription lenses, it's like changing from green to red glasses. Things can become harder for a long time after a perspective change - most studies I've seen on CBT for example show it's still good for longer term outcomes.
