If you want to support people, including yourself, in making changes or accomplishing goals, read The Progress Principle. The simple message: Research shows that if we can see our progress, no matter how small, we are motivated to keep on the path towards the change or goal. I can't tell you how many times I have recommended the book, or how many times people have read the book and then sent me a hearty "thank you."
For a quick overview of the book, click to watch this video (99u) of coauthor Dr. Teresa Amabile. In it she mentions that a person can track their progress in many ways including using an app; one example of this kind of app is iDoneThis, which you can download for free.
I finally decided to give Jerry Seinfeld's productivity secret a try. It's more commonly known as "Don't Break the Chain," and the concept is simple: spend some amount of time doing a desired activity every day and, when you do, cross off that day on a calendar. This creates a chain of Xs showing your progress. If you don't do your specified task on one day, you don't get an X and that chain is broken. It seems almost too simple to work, but it's allowed me to accomplish so much more than I ever thought possible.
And here's an app to support you in not breaking the chain: Wonderful Day.
If you have not already tried harnessing the progress principle, I urge you to give it a try.
Note: One of many reasons I am a believer in the value of the progress principle (other than that I have seen it work for myself and others) is because it is compatible with some of the solution-focused techniques, such as scaling. I have blogged about solution-focused approaches in the past, e.g., here, here, and here.
