How to determine what am I?

I know that my character traits, decisions I make, my hobbies, likes, friends, job, home and everything else around and inside me could be temporary and aren't fixed through my entire life. Thus, it wouldn't be correct to think of myself as a set of these temporary preferences. 

In the meantime, there is something I'm driven by, some force inside me that pushes me and helps me make decisions and take actions. Is it just complexes, insecurities, my ego that is trying to achieve something and fulfill its (or my own) needs? I don't really like the idea of thinking about myself as a bunch of anxieties, doubts and stresses, even though from scientific point of view we all are just bodies with some biochemical reactions going on.

So, has anyone figured out how to explain to answer yourself a question "what am I?" or it's impossible to answer until your last days of life when you have a full perspective of the life you've lived (this is just one of my assumption of how you can get to know yourself)?

Any related articles, videos, books are appreciated.

A question like that takes a lot of meditation and sorting through complexities and intricacies of your identity.  Simone de Beauvoir describes her realization when she told herself "I am a woman", a statement which seems so obvious and yet was so impactful to her identity and development as a human being.  Instead of searching for books, articles, videos, and hearing what other people say, look inside yourself.  It could take months of quiet time & long walks, but it'll be worth it.
