Some very shallow points, but this article looks like it only applies for the author.
I think its great that everyone knows why they are hesitant to do things, and I see some great comments here.
I've also been collecting my thoughts on why I'm "hesitant" as well.
I've made a site to document my thought processes.

I've also thought about other keywords such as "start" and "focus"

https://www.deepthoughtapp.com/en/topics/focus/
This process has really helped me better understand myself, and how I operate. I hope it can help others as well.
Just to flip it around, maybe "lazy" would be interesting as well.
