I think the trick is to pick the right goals for the chain method. Something like "walk 10 miles every day" is too constraining of a goal, because realistically there are going to be days where that is impossible (e.g. when you've got a 20 hour flight to China, or a broken hip.)

Instead, you need to make a goal where "work towards that goal" is not concretely defined so that you can do work towards that goal under virtually any circumstance. For example, if your goal is to get a certain time in a 10k race, then you can read books about race strategies or training methods on your flight and count it as progress towards your goal. If you're recovering from a broken hip, you can mark physical therapy or diet decisions as progress towards your goal.
