During the summer holidays this year, I thought I should do anything meaningful instead of staying at home, so I was got a job at a restaurant, worked there as a cleaner. I worked seven hour a day for three weeks. The job was hard and bored and seemed endless, which made me so tired that I nearly gave it in half way, but I stuck to it with determination. Every day I started off for work early in the morning and got home lately in the evening. Finally I finished the job before the new term begins. Now, I understand that labor means. I think it is really successful experience.
