NEVER GIVE UP! Finish what you start no matter what critics say or resistance you get. Persevere! Tell your story/ies.
Get them down! Let them be. Later, if they need fine tuning, go ahead and do that, but tell what you want to tell.
If for no one else, finish your story so YOU can see how it ends, even if no one else cares or if they lose interest. Someday, in the future, you may pick up readers that are into what you have to say and who want to live in your world for a while. Write for them as well as for yourself.
Be passionate! This is YOUR creation and it is worth exploring.
