I have a lot of faith in humanity, so much so that I feel joy just acknowledging life and humanity.
It irks me that people don't though, it seems so... misguided. We're doing better than we ever have before, and things always seem hard, but we're not going to fail anytime soon. People can be silly sometimes too, they can make mistakes, but the very fact that we acknowledge their misgivings and we learn from these mistakes shows that we're still human and more importantly, developing.
I used to call myself a misanthropist, but then I realized I was clinging to anger and being very judgmental, because things really are great overall and to think otherwise is to only view the negative aspects. Thing are going to be okay, just as we long as we stop getting this idea into our heads that the world’s a terrible place and we are without hope.
As for the environment, ect: well a temperature change isn’t going to wipe us out, war is becoming increasingly unlikely, and despite society's adolescent-like values and indulgent nature; we, like all living organisms on the planet, respond to change, both subconsciously and consciously and will adapt to resolve our issues, it’s only a matter of time. Not to be insulting, but I only really lose my "faith" per say, when I'm all depressed and "typical teenage angsty".
Things are pretty awesome.
