To make it as a creator, or really in any occupation, I believe you need to enjoy the activity itself. You need to enjoy, separate from any monetary incentive, the act of creating. Because while you can't guarantee any measure of success in any field or occupation, the part you do have control over is what you are doing each day to pursue that success. And if you don't have your heart in something, the pursuit of success will just constantly torment you during that daily grind.
