The future is bright for you man, keep that focus and strive to be the best. Quality work is pretty hard to come by these days and people do notice it when it is set higher than others.
Hunger and dedication are two very important qualities when starting your own company. Pay attention to what people are telling you and make it work for you when you can. As a young man starting out on your own I would really focus on continually learning. The only downside I could see from going on your own so young is that you won't have a mentor to guide you and learn new skills, not like you would while working for someone else. Letting someone else make the mistakes and you just sit back and watch and learn. Now you are the one making the mistakes and learning from experience rather than by observation. Don't let that discourage you though, learning on your own is truly the best way to learn, but the consequences can be tough to deal with.
I wish you nothing but the best young man, keep you head and quality high and you'll be just fine.
