Humans can be just like particles, and in comparison to the endless Universe in size and individual importance, that is exactly what they are.

Humans spend years eating, sleeping, working, and worrying about those things, but it is their free time that is most important. If spent well it can render them into great people, if squandered, it cannot.

Everyone likes talking about other people's flaws, less so their own.

Many people say all sorts of things, they usually do others, and they prove what they say even less.

Believe evidence, not people.

Best to be humble unless people are unreasonable then best to be direct.

There are indeed abominable ideas and beliefs which are of no discernible good, but we should not assume our ideas are so flawless that ever applies to entire groups of people.

Wisdom is not judging others by superficial differences but noting the almost endless similarity that all humans share.
