The Dalai Lama was once asked if he was ever lonely. He said "No". When asked what he attributed this to, he responded, "I think one factor is that I look at any human being from a more positive angle; I try to look for their positive aspects. This attitude immediately creates a feeling of affinity, a kind of connectedness."
This is an excerpt from a reading of mine recently and I just think it is too great not to pass on.
