I have a spreadsheet in that I have all my daily habits and I tick them off as I go. I make sure to include granular and simple habits, like taking my vitamins, drinking a glass of water and washing my face, etc. I also ensure that I keep it granular, so, putting my running clothes on is a separate habit from going for a run!

Then I have it color-coded, so I can see an overview of how many of my habits I am completing daily. It's great, the first time in my life I've been able to take vitamins on a daily basis, and journal every day!
