I decided to write a diary in English everyday

I know i am not good at English. So i decided to write a diary in English.

My diary must be bad but, it will be better and better.

Hmm... Actually it is hard to me keep a diary even in Korean. So i don't know what I should write.

Even i have just know that the sentance, 'keep a diary', is mean 'write a diary'

 

Now, I ask to my readers. Give me help. There must be wrong sentances or word, anything else does't make sense. Please correct me if I'm wrong. I will accept your help happily.
