I can take someone with the shittiest personality ever... if they even remotely cared at all. No matter how attractive someone is on the surface, if they have a shit personality, there is no reason for me anymore, and I'd have nothing worthwhile to even consider.
Are you feeling anger towards a specific person or towards people in general?
People can change. But the problem is a lot don't feel like they need to. When things are generally going their way and their gaining the most from what they're doing or how they're doing something, they don't think anything's wrong with what they're doing. Sometimes people do, and may make an effort to do something differently. Some will do better in their relationships. Their work ethic. How they treat others. But sometimes, they refuse because they don't like being wrong.
And sometimes you just have to let it go. There's no point in wasting time being angry at the world for something that won't change. There's a lot you can enjoy before your time is up.
I used to be someone who didn't even hate other people and strived hard to understand them better. I was a genuinely kind person, though if someone provoked me, I would tend to respond and it's not all that nice. I would try to be polite, but now I can't help but have a surging feeling of hate towards someone else burried deep inside me... It makes me want to call them out for being such a grand asshole and a bitch... It's not like I wish other people died, but this guy is special. It makes me want to throw a mountain to bury someone... If people changed, then I probably wouldn't hate them that much and I would be willing to accept it.
