Well somebody forwarded me about this Johari and Nohari windows. Here goes some details about it. I just copy it from the web, for your reading (too lazy to explain about this :P)
The Johari Window was invented by Joseph Luft and Harrington Ingham in the 1950s as a model for mapping personality awareness. By describing yourself from a fixed list of adjectives, then asking your friends and colleagues to describe you from the same list, a grid of overlap and difference can be built up.The Nohari Window is a challenging inversion of the Johari Window, using antonyms of the original words. By describing your failings from a fixed list of adjectives, then asking your friends and colleagues to describe you from the same list, a grid of perceived and unrecognised weaknesses can be explored.
Well then people, describe me. Describe the positive via the Johari windows, and describe the negative via the Nohari windows. And then try for yourself! (and give me the link so that I can describe you later heeee!). No hard feelings. Just say it.
