Ask HN: I Am Going in Circles

I am writing a piece of code for a web application. After deliberating on an approach I implement it. Then after I complete the code, I think of another approach and abandon the previous code and start writing new one! This has happened now for almost two weeks. I complete the piece of code, I am not happy with it. Then throw it away and start deliberating on a new approach and the cycle starts again. I am just going in circles! Looks like I am stuck. How to get out of this situation?
