Well yeah. At a certain point you've got to be really honest with yourself. Like 'Why am I doing this? What are my motivations?' Like if you get into it because you want to be famous? Then you've got a long row to hoe. But if you really feel like it's a labour of love and it's something you're actually legitimately good at then it's not that hard to keep plugging away.
As human beings we are endowed with freedom of choice and we cannot shuffle off our responsibility upon the shoulders of God or nature. We must shoulder it ourselves. It is our responsibility.
