This feeling of warmth is very important because now human beings are for various reasons becoming more and more cold. With mechanisation human beings are becoming more and more like machines, and one aspect of this is that they lack feelings. So having this warmth, having feelings for other people and for ourselves, is something very important, very beautiful.
Another point which might be relevant to some people is that loving-kindness can develop a sense of self-confidence.
We lose self-confidence when we consider ourselves as unsuccessful, worthless, useless, always failing. So it is a very negative self-image we have of ourselves, mostly as failures.
With more and more loving-kindness, especially towards ourselves, we can see how it works: we can see our own potentialities and we can become more and more self-reliant, and this can give us a lot of self-confidence in the sense that we can handle whatever arises. So it is not that difficulties will not arise; anger will arise, problems will arise, difficulties will arise, but you have the confidence if they arise: I know how to handle them, I know what to do.
