Start Job Soon

My winter vacation will be over soon. It was over in the blink of an eye. However, I think I had a great time since I spent most of my time enjoying different kinds of meals, doing Hatsumode and visiting my mother's grave with my family this year. I have to get to work again the day after tomorrow. I guess the first day back at work is always a tough one. I hope no troubles will happen at work.
As I ate and drunk too much even though I kept an eye on how much I would eat, I must lose my weight immediately (I'd like to lose 4 more kilos in one week). It may be a challenging mission for me. For the first time this year, I practiced volleyball yesterday. Volleyball is one of my hobbies. My hand-eye coordination was so bad that I failed at times. Perhaps, I suspect it is caused by increasing my weight too much. I'm kind of regret about it now.

Good job with your English!
