A lot of things can demotivate me. Being too tired (which is always), too stressed about life, if my kids have been a handful lately, not getting any story reads, my laptop being slow (my laptop is so slow that I end up messing around half the time waiting for it to load. I code and write pretty quick so my laptop really hinders me). And then of course there’s the usual writers block. It doesn’t happen to me often because I usually have a good general idea of where my story’s going, but there’s always a scene or two that gives me more trouble than the rest.
I just try not to put pressure on myself to write. I will never be a popular author because I take too long to update, but I cannot and will not force myself to write if I don’t 100% feel like it, because I don’t want to half a** what I produce.
