That is just the secret to it, there is no specific way or special way to go about it. You just have to find time and fix a timetable to manage your time, if not you might end up loosing on one aspect, it could be either on your job or your school work.Never really had a business like that on campus although I paint but it's a seasonal thing. My roommate in the other was a fashion designer and I can tell you for real,if you don't schedule yourself well,work could really affect your studies
