The more a person indulges himself the less others are willing to indulge him.

That little hypocrites and half-crazed people dare to imagine that on their account the laws of nature are constantly broken; such an enhancement of every kind of selfishness to infinity, to impudence, cannot be branded with sufficient contempt. And yet Christianity owes its triumph to this pitiable flattery of personal vanity.

He who cannot give anything away cannot feel anything either.

Self-interest is the enemy of all true affection.

For usually when people are self-centered, they are self-centered because they are seeking attention, they want to be admired and this is the way they set out to do it. But in the process, because of their self-centeredness, they are not admired; they are mawkish and people don't want to be bothered with them. And so the very thing they seek, they never get. And they end up frustrated and unhappy and disillusioned.

The individual who is self-centered, the individual who is egocentric ends up being very sensitive, a very touchy person. And that is one of the tragic effects of a self-centered attitude, that it leads to a very sensitive and touchy response toward the universe.
