Who am I?

The one thing that I am sure about myself is that I am a 35 years old man. Honestly, all other things that I know about myself or my family, friends, colleagues, classmates, lovers and haters think about me are not reliable. I never found that if I am an trustful person or a liar one. Whether I am an emotional man or a strict and serious one. Whether I am sociable or dissociable.
Frankly, the problem is that trying to know and learn about sciences, works, others, lessons, skills, unknowings and everything didn't let me know myself. I learned that Steve Jobs was a great entrepreneur but I never found whether I am an entrepreneur or a employee. I learned a lot about statistics and probability and learned how I can measure the probability of collision a plane with the birds in an airport but I never could determine my success in last educational and occupational careers. Although I respect family and desire to have children, I never had this chance to have my own family or I never had tried to make my own family. Despite excellent grades in high school and university, I never have ever worked based on my education. I have been a pet lover since I was a child but I have never had a pet. My life is a completely confusing combination of many many desires and diametrical achievements. Funny life!
In spite of all these mentally controversial issues, I don't want to complain my life because I love it. I love all days that I passed. From others' point of view I am a successful man and I BELIEVE it. But I have a question; Are the others' opinion true? Are they capable to decide where I succeeded or not?
I doubt whether I can rely on others' opinion while I can't rely on my mind. The main question is that who I am and I doubt whether there is an clear answer to this question. Is it possible to find the answer of this question?
