One of the most interesting things in life for me is to understand myself better. How do I react to my environment? And why do I react the way you do? Since I started thinking about myself I am able to work on myself. Patterns arise and understanding grows. Knowing myself allows me to playing to my strengths and therefore improves my personal happiness.
One of the things that I enjoy are self-assessments. A good self-assessment explains some facets of your personality. The most interesting for me was the Myers-Briggs Type Indicator (MBTI). In case you are interested: I wrote my personal result on my webpage. The quickest assessment so far was a PI assessment that I had to provide prior to my interview for my current job. HR draw a very precise picture of me just on the base of a few selections of mine. Stunning! I found another interesting test a couple of days ago. It is called PersonalDNA. I quite enjoyed it and realised that the results are quite consistent with what I know about myself. I quite like as well the Johari Window. Make your own Johari Window here.
Good luck on your own journey to yourself. Clearly, assessments are only a small step on the way. But nonetheless, please let me know if you know good assessments.
