To find out who we are, we have to take some time and do a SWOT analysis of ourselves. Wondering what is SWOT? Well, that is knowing your Strengths, Weaknesses, Opportunities, and Threats.
Dig into yourself and understand what terrifies you, is it the risk you take in life or the fear of failure. Many times we want to change our job, career, house, city etc., but we take back because we do not want to face the failure. We assume that we may not get success and we may have to face failure, and the fear of failure hold us back from trying something that we wanted to try.
Let us leave the fear and explore whatever we want to do in life. Only then you will understand who you are, and what do you want in life. Unless you try, how would you know whether you can do that job or not? Don't jump into conclusions based on assumptions and previous experiences.
