Aren't they already?

Do not make haste in judment.

Don't judge a person based on their appearance.

When i was a young girl, I saw that once a day an old woman with an ugly appeareance would appear in the street. People were scared when they saw her and I was too but the old woman did get upset when she saw this. She kept happy, confident, postive and energetic everyday.

I didn't know why but curiosity drived me to ask her. She told me it doesn't matter about your appeareance but it is important for you to keep a confident attitute about your life.

If you keep happy, postive and energetic you will look pretty and lovely. It can help you to make sure you are able to complete your first step of your goals.
Ok, where there is a will, there is a way. If you can set up your goal and try your hardest to make it come true, I believe you will succeed sooner or later.

A mistake.

I'm feeling really depressed. Yes, I can do English a tiny little bit but I can't get a feel for it.

Air of conversations, I have no Idea of it.<= Really not sure what you mean by "Air of conversations", maybe "gist"?.

So I tried to improve/practice by chatting with real Americans and other English speaking people but while I was (past tense) doing it I made a mistake saying something that was rude or so bad I think. Someone said to me 'I would go to kill you' or something that I don't remember exactly. I send messages saying "I'm so sorry" (to the individuals individually) but nobody answered me. I'm so sorry for those guys but it's really annoying that I do not even know what I said that went wrong. Eventually I left (past tense leaved) that community site.

I don't much care about internet sites or social networks but this time I feel depressed. Really.

 

I think the last two sentences are incomplete, I suspect you were trying to say that you didn't care that about what people thought on social network sites normally, but that failing to communicate with them this time has made you depressed? But that's a lot of guess work to fill that in.

 

Actually reading your entry, I can get a feel for where your at in your learning. Your far more advanced than basic English, but just falling short of fluent. Perhaps try kicking your English back a touch when your using it, keeping it simpler for a while, while you learn practice more?

Anyways I hope this helps. Good luck.

Just adding an answer to the above. Logically no, you can't be the best if there are three stronger teams. If it's a matter of opinion then it can be because it's your opinion. "We are the best team, even though there are three teams above us on the competition ladder"

Because I can't read the other language I can't tell you if it's correct. lol, btw this reads like someone's homework. More important than doing homework is understanding what it's teaching.
