Reverse-procrastinate 

Keep putting off something fun an excessive number of times so that you can be happier in the future.

I reverse-procrastinated eating my ice-cream for so long that it got freezer burn.

Reverse Procrastination 

When one finishs a project long before the due date and then forgetting about the project completely.

Reverse procrastination can lead to lack of editing, forgetting the due date, or losing the project completly.

I completed a project two months before the due date, but because of reverse procrastination, I forgot where I put it.
