How do you stick to the process once you’ve decided to be a professional writer? Remember, the only difference between a pro and an amateur is that the pro makes the habit of writing (whatever their schedule allows). They go back to the work. They make something of it. They don’t give up even when the work is complete crap and everything seems to be telling them they aren’t good enough.
What keeps you going? Where do you get your inspiration? What motivates you? Brings you back to the page time and time again?
Unfortunately, I can’t answer that for you. I have a hard enough time answering it for myself some days. But let me suggest that writing is only hard when we convince ourselves it is. Try looking at it as if it were fun, a chance to problem solve and express yourself. Tell yourself writing is your favorite thing to do and what gets you up in the morning.
Repeat that every day until you really do believe it. As in, fake it until you make it. Because the fact of the matter is that the muse only comes to those that do the work.
Inspiration can only get you so far
What happens when you don’t “feel” like writing one day? You do the work anyway. Find what keeps you going, but don’t let yourself stop even when that thing isn’t working. Make writing a habit.
