I weighed myself weekly to begin with, but once it became clear that I was going to be a serial-staller, I stopped weekly weigh ins and went with bi-weekly to monthly. As I got closer to goal, I weighed myself less and less, letting months go by. I found that actually really healthy, mentally. So I hit milestones like "under 100kg", and finally "goal weight" without even realising until weeks later.
Obsessing about the scale isn't helpful. I could feel my clothes getting looser, which was much more significant, and I was sticking to my plan so even when weight loss slowed down, I knew I was heading in the right direction.
