today was a good day

Today was a good day. I will have everything what I will want!!! I know it.

Hi, Oleg. From your article, I am not sure if you are writing it in the past or future tense. If in the past tense I would suggest a few amendments: The main words in the title need to be in initial capitals.

Today was a Good Day

Today was a good day. I had (will have) everything I wanted (what I will want)!!! I knew (know) it.

If writing in the future tense, I would suggest as follows:

Today will be (was) a good day

Today will be (was) a good day. I will have everything that (what) I (will) want!!! I just know it.
