@Promise_Michael write!
It doesn't matter who's reading...at least, not at the start. Like you said, finishing is what counts. Look, no matter how crappy it is, finish it. Once you do, you'll feel accomplished. And instead of struggling to write, you'll be polishing.
I started a new project about three months ago. I'm still on the first draft. It doesn't matter. It takes a great deal of time...years!
Check the profiles of wattpad stars...I always, always check their starting date. They're 2012, 2013, 2010...highest 2016 and even then, they were writing before wattpad. It's all time, babe
