How to align my life with my soul purpose?

My name is Arjun Kumar, born on 21st August 1990, 4:15 PM, in Mumbai. I am also a hardworking and ambitious individual but I always feel that I am on the wrong track as much as the effort I invest. I sometimes have doubts about my decision a few years later and want to start all over. Having been in this continuous state of self-doubt, I am left wondering, am I even aware of my true strengths and personality. I am interested in what sort of work, lifestyle, and life purpose matches my soul purpose. Will my birth numbers make me better understand my true calling and lead me on the way to a more meaningful one?
