The psychology of making and maintaining lifestyle changes

I have been working as a researcher in the field of behaviour change for several years now. I wish I could call you over and quietly whisper into your ear the secret of keeping up positive changes in your lifestyle. Of course, there isn’t a magical secret, but there are a few things that can help, whether you are giving up smoking, trying to eat a healthier diet, starting regular exercise or any other positive (and often difficult) change in your daily life.
