If you aren't living your dream, you are part of someone else's. Do exactly what you love and what feels right and brings you happiness. Do not be concerned with how you will make money or survive, if you are doing what you love, the money will follow. And don't think that what everyone else around you is doing is "the" right way to live your life. Everyone has their own calling. Some people want to help with others dreams and some people want to pursue their own. You always have a choice. Whatever you decide, pour your heart into it and make it the best it can be, and be the best YOU can be. Doing anything halfhearted for yourself or somebody else isn't worth doing at all.
And above all, for real, true, business advice, always put your customers first, read every book you can get your hands on and always think about the person you are serving. Without happy customers, there is no business.
