Last winter vacation, some of my classmates decide to travel with their friends, while I chose to take a part-time job to gain experiences and earn some money. I learned from my teacher that a nearby company was looking after students with good handwriting to write addresses on envelope. The pay were 10 cents per envelope. I headed for the company, feel sure I would easy finish 300 envelops in five hours and to earn the money. Actually, I only finished 200. Now, I fully understand how hard is to earn money.
