Everyone is forgetting. The words for you are- usted, tú, ti y te. It all depends on what you are trying to say.
¿Cómo te llamas? (informal) What is your name? o What do you call yourself? ¿Cómo se llama usted? (formal)
Te amo o Te quiero. I love you. o I want/love you. Te is used before verbs to reflect that action to "you" (the person that you are talking to.)
Es por ti que soy feliz. It's by/because of you that I am happy. "Ti" comes after "por", "para", and "a".
El regalo es para ti. The present is for you.
Just a little note-
Very often ti is misspelled as tí., or they are thought to be two separate words. Tí does not exist. Some people think because there is mi and mí, there is the same for ti. By the way mi translates to "my", and mí translates to "myself".
One more note 
Talking about "tú" and usted, like said by another member, tú is used for people that you know well, but also for people your age or yonger, even if you do not know them. Also works the other way, even though you may know someone older you still want to use usted to show respect.
You would refer to yourself as yo in most instances, unless you were showing possession.
Since you joined this site, why don't you take some of the lessons. It will only take a few minutes of teaching here to clear up the question you just asked. In addition, you will learn many more words.
tu, if you know the person real well. Usted, if its some one you barely know.
