Finally, I stood up and tried to give my best shot to my daily life even though it is a routine and doesn't satisfy me at all. To have a fruitful and happy life, I needed something more strong stimulant  (stimulating). or incentive so I picked up two things:  one is to study English again which was one of my favorite subjects in my middle and high school and the other is to be into some sports regularly which are badminton and marathons.

 I hope you understand how I felt with my boring life in the past and how I changed my mind these days.

 Don't forget that you are one of my supporters. because I recovered my confidence to some extent thanks to not only your cheering words in a class, but also your best attitude to try teaching your students including me from your heart. (it's better to make this into two sentences rather than one long sentence, I think) 

Thanks again and see you first week of April.

**Mickey, this diary was so great to read.  Thanks for your complements at the end.  You formed some rather advanced sentences here, with good structure and grammar.  You are really improving!  Great job! :)
