The ghosts of abandoned projects

I have crazy ideas.  I have bad ideas.
I have ideas which I implemented but eventually abandoned.

I wanted to have a webcomic, so I made one. But then, I abandoned it.

I wanted to have a visual novel, so I wrote the story. But then, I abandoned it.

I wanted to write a book to sell, so I enrolled myself in a 22,000 peso worth of online course to know the trade. But then, I abandoned the drive to push through.

I have abandoned a lot of projects, and their ghosts are haunting me.

How does one deal with a ghost?
