First Diary Entry

This is my first time trying to writing a diary entry in English. One of my friends told me that keeping a diary everyday is a very useful way to improve my writing skills. I believe it this is true. So I am doing it now.

Now it is at noon ("It is noon now" sounds a little more fluid), nothing special things has happened in the morning so far. I woke up at about 7:40am; it is a warm day for me. (Do you mean the weather was warm when you woke up, or the weather has been warm since you woke up? If it has been warm since you woke up until you wrote this journal entry then you should say "It has been a warm day for me." If you were writing this journal in the past tense you would say "It was a warm day for me".) After I did some washing and brushing (make sure to be specific such as "washing my face" "brushing my teeth" "brushing my hair"), I had breakfast. My breakfast was very simple easy, just some one milk with a slice of bread, then I went to work. I know I am writing just like a primary school student. Maybe even worse than a primary school student. But if I never try I will regret it later......

Note: Don't forget proper punctuation. The first letter of a sentence is always capitalized, as well as the word "I".
