How does one gain the motivation to write? I have an entire fictional universe in my head but can't seem to get it on paper. Any thoughts on something that could help?
just start out trying to write anything, and create it in some way. if you still can't do it, lower the stakes, and reduce the size and magnitude of the thing until you can do it. then congratulations you did something that is all your own. now do something a little bit bigger, or do 10 more small things then by then you should be ready to try something slightly bigger
