I have friends who testify to many started but never finished manuscripts. Their virtual drawer bursts with the begun & abandoned.
When I was a wee child, I had many such stories. Half-written real paper pages (that was a pre-digital age) not mellowing but yellowing from neglect, lay next to other unfinished arts and crafts projects. They accepted their destiny to never arrive at a destination.
That all changed in my late twenties.
I worked for a friend who is also possibly the most talented artist I have ever known. I saw the chest of half-done and abandoned textile work that was her life then, and it scared me.* I made a vow, not to another person or the creator, but between me and myself. From then on, I won’t give myself permission to begin a new work until I finished the one I had started.
For me, that vow was one of three best private decisions I ever made.
This is not for everyone. Nothing is. But if you are plagued with many “someday I’ll get back to__” started projects, my wish for you is that you find your way to a clear that cluttered path. My “how to” may sound harsh, but harshness may be what’s needed.
I find half-done manuscripts a sad sight. For me, only real life gets to be a never finished story. That is, until it, too, comes to an end.
* I'm happy to write that my old friend seems to have conquered the issue as well, as her amazing creations are now sold by the finest galleries.

If two can,
you can too!"
