Interesting Segmund...although, I do not agree that we can't change our physical appearance, our social position and financial status. Many have. In fact, I believe it is easier than changing our bahaviour.
Changing behaviour necessitates the ability to analyze what we do wrong, which necessitates the ability to admit fault. Not something our ego is eager to do. And changing behaviour, a habit, is in most cases, a lengthy process.

All not things people are keen on.
