Or you could try @musera’s reward idea, there’s a website and app for your phone that you also have to manually set goals yourself and hit your mark - only this one doesn’t charge you any money. You level up an RPG character and are able to win gold to purchase better equipment and fight monsters. It’s called Habitica.
(I was doing it for a while, but because of the “manually enter data” part, I fell out of doing it after about a month. It was just one more thing to do everyday (and so I literally had a goal to check of doing Habitica every day within Habitica) so I ended up dropping it.)
There have been at least one if not two or three threads on the subject, there was even a group of people on the forums all doing it together. Maybe I would have kept up with it longer had I been a part of that “party” instead of my two-person one. But I digress…
