Sales is my cup of tea?

Hello. Good morning may I speak to ......... After one n a half month taking this job, I found that doing sales is not easy. Everything u said (phone conversation, appointment with customers) all is Arts. But one thing I like is I can always going outside meet customers. Though i know from my childhood till now I'm the person who like to entertain people or make people fun. If u cannot change the environment, u must self-changing (改变自己) . Though this is my first job - sales engineer, is quite a self-motivating job. If I do not work hard, I won't have commission apart from my basic salary. Everyone knows the first job will not last long. Hope I won't easily find another job. Actually I'm not satisfy why M.C. will become unpaid during my probation. What if I fall a sick for one week ? Then my paid will cut down for 1 week. It's terrible.. terrible. Why during probation Saturday is compulsory to work half day instead of alternate. Like this Conclusion, my boss is a stingy, kiam siap person. Hope my probation will fast fast going through.
