yeayy! iim so proud of myself. n u wanna know y? its because i managed to change my room's fluorescent light. Haha. At first it was quite vertigo. Im not a person who's afraid of height. However, with the non-balance ladder i used, it made the fear of height escalating. But after awhile, i got used to it and easily i changed the fluorescent light. Regardless anyone's guidance. HUH!
