These questions are very good to think about.
What makes me different from all the other photographers, who are A LOT better than I am, is the question that almost made me “throw” my camera to the closet and leave it to collect dust. What kept me into photography was the thought that my life and views are different from everyone else. It’s part of my story where I can see my progress where I was when I started to where I am now, trying to understand and get feedbacks: “Is the photo good?”, “What I should change?” and etc. I don’t travel around the world, I’m not professional, but I am still young, I keep learning and maybe one day I can travel around.
Mostly I do this for myself. It’s just one of my hobbies and feels freedom for me, because I can have time for myself, I don’t have to rush on my days off from work. I like to share my works with everyone, including with my friends and family, who always think I’m very good at it, but strangers, who know most about it, give honest opinions. Those opinions give me more hope that I can become better and I put more effort into every next photo I’ll take and post. I'm not gonna give up on photography any time soon like I did with guitar play.
