I used this system for a couple of months while I was putting together a more permanent solution for it. In my system there was two kinds of habits: stuff I did or did not do and habits where I rated them 1-3.

This is how I did it. I started by writing the date: - 2022-01-01, underlined it. Then I prefixed all the rates with * and the habits I did with -. All the habits was summarized as ideally one work but no more than three. It usually looked something like this

2022-01-01:

• Diet 2
  
• Exercise 3
  
• Money 1
  
• Brush teeth morning
  
• Guitar
  
• Run
  
• Rowing
  
• Walk
  
• Yoga

It worked really well as a paper solution to it. And I will without a doubt move back to it if I want to do it on paper again.
