Altruism is the best source of happiness. There is no doubt about that.

As far as mental development is concerned, we should never be complacent. We can develop our minds infinitely - there is no limitation.

...it becomes clear that, given our diversity, no single religion satisfies all humanity. ... And since the majority does not practice religion, I am concerned to try to find a way to serve all humanity without appealing to religious faith.

No matter what activity or practice we are pursuing, there isn't anything that isn't made easier through constant familiarity and training (I think you can apply this to soccer as well)

I think when tragic things happen it is on surface. It is like the ocean. One the surface a waves and sometimes the wave is very serious and strong. But it comes and goes, comes and goes, and underneath, the ocean always remains calm. Tibetans have a saying: "If bad news comes to you listen here" (points to the right ear) "and let it our here" (points to the left ear).

Conversion is not my intention. Changing religion is not easy. You may develop some kind of confusion or difficulties.

If you want to be wisely selfish, care for others
