Heya! I struggle with motivation too!
I find often that just forcing myself to get it done works, because you can allow yourself to write literal garbage and then improve when you check over before publishing. Do you know what I mean?
Also, find things that inspire you, that will HELP you to stay motivated. For example, I listen to a lot of music and ambience/ASMR, and that keeps me both inspired and motivated.
I also find that thinking of how my readers will react to my work keeps me motivated.
^ These work for me, so just try them out. They may work for you :)
