I've made a nice little excel sheet which I use to help myself do good things and hope it'll be a good contribution to TRP. I've already filled in some of my own habits, so use them as an example.

Uploaded into Yandex (kinda like russian Google) Disk. So if it's on russian, you can find a toggle on the lower side of the page.

It uses macros, but nothing harmful, just a few lines which fill in a date (when happened first time and most recent) of occurrences into adjacent cells. Sadly it takes a little while to load thanks to aforementioned macros.

Feedback is greatly appreciated, feel free to twist the sheet in any way you want!
