Respectable Mr. Anderson, 　　I am sorry to inform you of my decision to resign my current position in this company. 　　I appreciate the opportunity of having worked here with you and other colleagues. The experiences will be unforgettable throughout my life. However, unfortunately, I find this job quite below my expectation. First, I have to say that my salary is far from satisfying, which can barely sustain my life in this expensive city. What’s more, the responsibility I’ve undertaken is not challenging enough to enhance to practical abilities. 　　I look forward to an approval of my resignation, and apologize in advance for any inconvenience caused.
