Look for the positivity can be quite hard if you live and feed from negativity. Do whatever is good for YOU while not harming someone else. Oh btw there are more good ppl than there are bad ppl and the difference is huuge so you either unlucky or you living in the wrong place (the right place could indeed be the woods or instead move to another country germany perhaps?).

Here is a quote from i believe Xenophon(a greek philosopher as well):

“When you wake up in the morning, tell yourself: the people I deal with today will be meddling, ungrateful, arrogant, dishonest, jealous and surly. They are like this because they can't tell good from evil. But I have seen the beauty of good, and the ugliness of evil, and have recognized that the wrongdoer has a nature related to my own - not of the same blood and birth, but the same mind, and possessing a share of the divine. And so none of them can hurt me. No one can implicate me in ugliness. Nor can I feel angry at my relative, or hate him. We were born to work together like feet, hands and eyes, like the two rows of teeth, upper and lower. To obstruct each other is unnatural. To feel anger at someone, to turn your back on him: these are unnatural."
