It's the will to see things through. It's like trying to fix a broken water pump. I use the pump since I had the other day. You know the mechanic and what problem it has. But, nothing works. You can't ignore that uncertainty. It keeps bugging you and urges you to get back and see things through.

The pump started working again when I I hit it with hummer. Maybe something was stuck at the button of its chamber. I don't know, but it's working. I cleaned it thoroughly and made sure it didn't stop before installing it back.

I lost myself here with this pump. Anyway, that uncertainty will keep you around until you find something that can fade that feeling. Of course, it will be something with bigger uncertainties hahah.
