Last winter vacation, some of my classmates decide to travel with their friends, while I chose to take part-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, feeling sure I would easy finish 300 envelopes in five hours and to earn the money. Actually, I only finished 200. Now I fully understand how hard is to earn money. Getting out of the classroom is indeed necessary for we all.
