According to what I have learned from Business Communication class, perception is a process of making sense out of experience toward issue or topic. Self-perception is knowing about oneself in both positive and negative way, know what and why you think or like toward the issue or the things. For example, I like reading marketing books not because of my parents want me to read or not because of the suggestion of lecturers but I read it because I like marketing and I think it will be useful knowledge that I can use in for my future career. Another example is I am a member of PSU Martial Art Club and I choose joining this club because I want to learn how to protect myself from any bad person or the accident in the emergency case and it is also another good way to exercise. For the negative side of my self-perception is I am sometimes lazy doing the assignments so I have to rush for it in few days before the deadline.
