How can I build small daily habits without feeling guilty when I miss one?

Make the habit very small, decide ahead of time what you will do after a miss, and judge the week instead of the day. A habit that takes two minutes is easy to resume, and a restart rule such as doing the smallest version the next day removes the need to debate. Talk to yourself the way you would talk to a friend: that is fine, today is a new day. One missed day is a small gap, and the habit is only in trouble if you stop trying again. Migachi, an iPhone app coming soon to the App Store for adults 18 and older, keeps goals small on purpose. You pick a few daily goals, tick them when you can, and your pixel pet is happy to see you each time.
