Do I Have to finish This?

A few hours ago my friend reminded me that I have a thesis to make. I totally forgot about it maybe due to the long break. A few years ago, I decided that I don't want to pursue this anymore because it was costly and simple. But a while back, a friend convinced me otherwise so I enrolled for my thesis. However, completing this is not one of my priorities. But deep inside me, something tells me that I have to complete this thing. I have to finish everything I have started. I must constantly remind myself that I have to start it first in order to finish it. Getting confusing, am I?
