How do I stop being so cynical?

I understand, its hard to find genuine people nowadays. But your bitterness and resentment will just be a heavy burden to you. Just avoid the cheaters, backstabbers or the people who you're sure are not worth ociating with. You will be happy if you will ignore them, treat them as if they dont exist, cause if their nonexistent, they wont be able to annoy you. Somehow you will find someone who is a complete opposite of them, although its like looking for a needle in a haystack (a bit cynical myself). You wont find them if you will be cynical and quick to judge a person. If you didnt like a person in your first encounter or heard something bad about him, it doesnt mean that the person is not good. Give the person a chance and get to know him first.
