A bad person do things negatively. A good person do things positively. A bad person curse others all the time. A good person cares about others all the time. A bad person talk in rudely manner. A good person talk with polite. A bad person sing along with the wrong faults. A good person sets others on the right track.
And there's more. You know it yourself. Look doesn't even matter. It's all bullshit.
Doesn't mean a clean look person, they're always good. Doesn't mean with a dirty drawings all over person body, they're always bad. They may look real clean from the outside, deep inside them, you won't know. They may look real bad due to their dirty drawings from the outside, deep inside them, you won't know.
You won't know until you know them. Stop judging them by how they look. Doesn't mean the good, is always going to be good. Doesn't mean the bad, is always going to be bad.
People change, it takes time. It won't change on the spot. Stop all this criticizing. You're making people around hate you.
Yes, learn to make them love you. Love them for who they are. Advice them is enough. Learn to except them.
Don't feel guilty. Not blaming anybody. Blaming own self. Didn't think twice.
You got no choice. No time to turn back. Stop thinking about it. Just go with the flow right now.
