Reply to Ever Felt Like Quitting?

I feel stuck. I love music and the art of music production don't get me wrong. Anymore though, I feel like whats the point of it? I see guys like Avicii and Porter a year older than me (Porter is actually younger) tearing up the world with their mixes and songs, and I just wonder whats the point because of guys like that. I realize it may seem like I am doing it for the wrong reasons, but i truly love seeing what my potential is. I guess I am just looking for support. I am in college studying finance, and I am constantly told to stop wasting my time, as it will never become a career and i will never do anything but weddings. I understand the point of what they are saying, but playing music is what I enjoy doing. I am just wondering if anyone else has been in the same boat and how you got through it. As I sit here just staring at my screen, I feel like I am at a crossroads. I have invested thousands into gear not to mention hours upon hours of my time to just stop. But then again I feel like these people are right at times, and that I should just play videogames like typical teenager. I feel like I could have talent, but I am not sure how to properly display it. I have no musical background and understand why people would say to stop. I do not know how to play the piano, and everything that I do know about music theory I have taught myself and learning from youtube has helped. Never did I expect to just plug in my Axiom and believe i would sound like Avicii, but damn am I confused. Advice would be appreciated if you have had this experience. Thanks
