Did you keep it up past week 6 or did the notebook end up in a drawer like most of my attempts at stuff? Tbh I used to roll my eyes at this whole tracking thing. I figured I knew what I spent and writing it down was just homework for no reason. Then my card statement showed 11 coffee stops in one month and I wanted to throw up. So I grabbed a cheap notebook and started writing every single thing down, and the first month alone I found about 90 bucks of junk I did not even remember buying. Turns out the notebook is not the point, it is the ten seconds of actually seeing the number before it leaves your account. Keep going past 6 weeks if you can, because that is around when it turns from homework into a habit.
