I took a month-long sabbatical last Fall to learn a new skill (machine learning). I had a project goal to keep me focused on making progress and staying practical: making an ios app that will use ML to "recognize" the letters on a Boggle game grid and "solve" it, printing out all the words on that grid. I made large strides during the month but the project wasn't quite working at the end. After the sabbatical it was back to work at my dayjob and I had a lot of motivation but little time, so I kept telling myself, "No time to work on it today, but I'll try tomorrow."

After a few weeks thinking this and not doing any work, I despaired that my project would end up as vaporware, blowing away in the smoke of my good intentions. So I started a new habit: Committing to work on it, every day, for just 15 minutes.

I use a pomodoro timer (Vitamin-R) and note-taking app (EverNote) to do my daily 15 minutes. Each time I start, I write down my goal for that session, and keep a running list of things I think of to do but don't get to in that particular session. Every day I successfully put in 15 minutes I mark off that day on a 365-day hanging wall calendar that is on the back of my apartment door.

Results:

* I have worked on the app for 90% of the days this year.

* I absolutely got it to a "working" state (I am now facing a diminishing returns problem where I'm putting in too much time fiddling with UX and UI polish, but that's a problem I'm happy to have).

* On over 50% of the days I end up working more than 15 minutes.

* On days when I feel like going longer, and have the time, I'll still occasionally hard-stop at 15 minutes. This gives me something I'm eager to come back to tomorrow, and also (I think) helps to engrain the habit. I want my subconscious to always think: yes, the cost of starting my session today really is only 15 minutes, I will do this even if I don't feel like I have a lot of willpower today.
