When you think that you're too good.
Your head gets too big and becomes impervious to any form of advice. You would refuse to listen to the words of others, even when they mean well, even when they want you to fix your petty little flaws. Stubborn, indignant, reluctant to listen to others and refusing to improve on yourself, just becaues you think that you're too good.
As a result, some of such people are not well liked by most people. But still, some people like such people. Weird people.
When you think that you're no good.
What to say? Your ego is ruined. You think of yourself as nothing. You could go in three directions once you've reached this stage.
(1) Think better of yourself, fix your problems.
(2) Whine to people. But to no avail, people get weary of you.
(3) Keep things bottled up within yourself. You might end up suiciding or self-mutilating as a result.
Of course, don't do option (3). There's just so much in life to live for. Cutting yourself doesn't make things any better.
Option (2): How does whining actually solve your issues? Fix yourself. People can't always be patiently listening to your bullshit forever.
Option (1): It may seem tough, but if you try hard enough, things will look up. Your life will change. Unless you're cursed or something, that's just sad.
Either way, don't keep this attitude. Normal people don't like such people. Unless you join some emo gang or something, maybe then you'd be well liked there. I'm sure not many people would like to go that way.
When you never think about yourself.
Selfless people. Always helping others. Always sacrificing themselves for the sake of others. Isn't that nice? Wouldn't such a person make a wonderful friend? But sometimes, such people are reckless, so they can be quite worrying. Such people are also rare.
When you think you're up no good.
Well then, destroy yourself before your evil manifests into something even more vile.
OK, enough crap here.
