@retrospacekid Hi! Don't worry, you're not bothering me at all. :) As you must have already noticed, I'm not the best person to answer that question, because I couldn't even manage to update one single chapter this year.
Perhaps you have to figure out why you can never complete your stories? Is it because you lose interest in your story or writing in general?
Maybe you could join some clubs here on wattpad, that might help you to get motivated an even get advices from the club members. :)
