There are only a few things I, personally, believe; one of them is the 'Golden Rule'. To treat others as you'd like to be treated. As well as, not mistreating others in a way you would not like to be treated.
Another idea of belief: we should all love openly, outwardly, and indiscriminately.
I have been conducting my own personal experiment on human psychology, and everyone I encounter becomes a 'test subject'. I have been analytically observing those around me for the past eight or nine years now. Let's just say that, I've come across many people from all walks of life with varying backgrounds, and have come to the conclusion that our race would be a lot more successful if they were to eliminate the word 'me' and 'I' from their vocabulary and thought process. Speaking of 'thought process', stupid people come in all shapes, sizes and colors. I don't necessarily mean 'stupid' in the academic/book smarts way, but rather more along the lines of 'common sense'. It seems common sense is not as common as I remember it to be as a child. But, there ARE good people out there too. You may just have to sift through a lot of shit to locate them. Further more, a fraction of those people are people of great value, and worth the time and effort.
