I've just finished reading Switch by the Heath brothers and I would highly recommend it.  Very good story telling and very broad references.

A quick summary (using different words):

Identify What to Change To

Motivate the Change
  • See-Feel-Change over Analyse-Think-Change
  • Shrink the change.  Aka the change sparcity principle: Do not change faster or more than necessary.
  • Cultivate identity and a growth mindset.  See also Mindset.
Shape the Environment

  • Change the behaviour by changing the situation.  See also Influencer.
  • Encourage habits using action triggers
  • Cultivate social motivation and support
