Be prepared for times with a roller coaster of ups and downs financially and emotionally. I believe that when you are doing what you are meant to do and what you love to do, that really helps carry you through the tough times. Never stop creating, thinking outside the box and improving your skills. Strive to continue to find new ways to improve the lives of others with your skills or product. Be okay with the fact that some of your great ideas will turn out to be not so great, and that's ok . Don't give up. Good luck!
