This seems to me a healthy thing, and most people in the helping professions would be only too pleased if their clients had more of it. What is often called love is a kind of addiction, or what is nowadays called co-dependency, and this is quite unhealthy. But if people can give more love to themselves, they are better able to give it to others and to accept it from others in a genuine way. This is a general feeling of being convinced of one's own pre-eminence. Ego-boosting leads to this.
Egotism always sees things in terms of better and worse, so it is always having to prove something.
This is not something which anyone I know is trying to foster. This is looking after one's self-interest with blinkers on. This kind of selfishness can only see what is straight in front of it. It is a kind of tunnel vision. It is as if the rest of the world somehow did not exist.
