There was an interesting grid developed in the 50's, to compare one's self-assessment with how one is truly perceived by others.
(Read more about the Johari window.)
There's an online test w/ database for both the Johari (positive) and Nohari (negative) windows that you can take and store your results, then have others go to your link and describe you as well.
- Johari test
- Nohari test
If you do this test, feel free to post the links to your particular pages in this thread so that others can offer their own feedback/descriptions and help you see yourself from another angle.
If you'd like to discuss the Johari/Nohari windows, feel free to post here as well.
Note: Obviously the Nohari is a negative assessment of oneself (i.e., weaknesses). If the idea of getting some [constructive] criticism bothers you, feel free to just do the positive Johari window.
