Having an end goal in mind is key to keeping you moving. If you didn't have an end thing that you wanted what would you have enough faith in to fight for. No one ever talks about the hard times. Its a pride thing. It doesn't matter how deep the motivation is for doing something, at the end of the day we sometimes question what its all for.
This past week I held my brothers daughter, she fell asleep in my arms. I could of stayed there forever but I packed my things and left to go back to New York. Every fiber of me asked, why leave love? There is so much love in my family, why would I leave to go somewhere so cold? What is it all for? As an artist we all ask on some level these same questions. Its a tiring game of explaining, pursuing and convincing and sometimes all you have at the end of the day is yourself (hence my song called Believer). You have to keep it alive everyday. Its how you make it through the bad stuff, trust me sometimes it straight up knocks me on my ass but its how you breathe life into it again that matters.

"Every creative journey begins with a problem. It starts with a feeling of frustration, the dull ache of not being able to find the answer. When we tell one another stories about creativity, we tend to leave out this phase of the creative process. We neglect to mention those days when we wanted to quit, when we believed that our problems were impossible to solve. Instead, we skip straight to the bbreakthroughs. The danger of telling this narrative is that the feeling of frustration – the act of being stumped – is an essential part of the creative process. Before we can find the answer – before we probably even know the question – we must be immersed in disappointment, convinced that a solution is beyond our reach. It's often only at this point, after we've stopped searching for the answer, that the answer arrives. All of a sudden, the answer to the problem that seemed so daunting becomes incredibly obvious." --Jonah Lehrer, "The neuroscience of Bob Dylan's Genius"
