I found out that I was an INTJ when I was about 19 years old (give or take a year). At the time that I took the first personality test I was having problems being myself after a 13 years of impressions that what I was was unaceptable by just about everyone that I met. So when I saw the results, and that I identified with the results, I felt happy and relieved. I wan’t alone. Who I was was good, valuable, necesary, and acceptable. I finally had a theory that could explain who I am, and who I’m not. I liked what this theory had to say because it wasn’t judgemental about who I am, contrary to everyone around me. I would have the words to describe myself that fit what was going on inside. That meant a lot. It was a turning point in my aceptance of myself.
When I found out that I was an INTJ my journey towards self knowledge took an awesome turn, and I was able to understand myself better than ever before.
