Having doubts

 I had another idea for a story and and first I was fairly excited about it. It's about a special needs teen who goes missing into another dimension. It's one of those ideas that came during sleep and wakefulness. That night, I spent a few moments really thinking about it and coming up with some plot points. I made sure to go over it several times so I wouldn't forget it when I really woke up.

The next morning, I fire up my laptop in order to add this story to my idea tracker. Once I got the spreadsheet open I saw that this was going to be idea #44!!! That's 43 other ideas ahead of this. Then I got discouraged. All these ideas and it's so hard to complete just 1. I've been working on Sherita Jean Jacques for 3 years at this point. I need some help FINISHING these ideas :-(
