I'm feeling tired.
A pile of books is on my desk. The desk is messy...
In the Internet, I found  different ways to learn English but did not find any easy one. It needs to memorise lot of words and sentences for effective use of english. For this purpose, I must have to work hard . although others help can excel my ability to learn, but best help would be if i help myself and my books can also help me a lot. Although I spent a vast of time for learning English, but it is still terrible. Thats why sometimes I feel disappointed.
This summer is hot.
I need to do work, to study and also a girlfriend. Er...Ofcourse, weather is weather, trouble is trouble.
Yes, I'm Ok now. Maybe you have the same feelings as mine. So, wish both of us a good luck !
Its time to sleep.
Bye, everyone.

*I try my best to correct.

It's 1:27 am in the mornig right now. I'm tired. A pile of books is on my desk. The desk is a mess. I found a way to learn English on the internet. I tried many different ways but every other way is very hard. A lot of words need to be memorized. A lot of sentences need to be memorized.
It requires hard working by myself if I want to be able to use English very well. Only I and my book can help me. It will take a lot of time to learn English because my English is terrible. Err... sometimes I feel disappointed.
