I am near perfect. But she needs to change
It is sometimes consoling how stable personalities are. And sometimes disappointing. I was struck at various school reunions how little people had changed, despite the great range of paths that life had taken them on.
I have seen big changes when people have decided that there is something about themselves that they do not like. I can think of quite a few people who decided to get fit and lost a lot of weight. It usually helped their careers.
The fit version was more attractive to employers than the fat version. Their confidence increased, though the fundamentals of their personality remained intact. If they were kind to begin with they stayed kind.
