I finally start working on my thesis today, I had written the introduction section so far. It’s a good start. I found it quite hard for myselt to concentrate on doing one thing. There is always a urge to do something else and I have to fight hard against it. Actually concentration is not only a must in study, it also needed in playing badminton. Today during the game, I found that when I’m concentrate, I can get the birdy with much more accurately. However, my concentration ran out after I got tired in the first two game. Keep up the hard work and carry on my 200 hours workplan.
