Self-centred people are motivated by guilt. They are incapable of being objective. They do not think for themselves. They think for other people. They are a danger to others.
Every genius has a grudge.
Time is change, not worth measuring. If two people want to get on with each-other, they will. We love what we identify with. We identify with the inner nature of the other entity. When people argue there is a mutual lack of understanding and respect.
