Goodreads asked Joshua Gayou:

How do you get inspired to write?

Joshua Gayou Inspiration is overrated. In my (admittedly short) experience, waiting around to be inspired is a fantastic way to never finish your project. It's great when inspiration hits and you want to try to ride that wave for as long as you can. But there is no labor lasting longer than a few hours of which you'll enjoy every moment. There are points where the process is going to drag and it's going to feel a lot more like work than play. During those times, your personal level of discipline is going to be a much bigger factor than any sort of inspiration.

Inspiration is only useful for starting the job. Discipline is what gets it done.
