Eighty per cent of New Year's resolutions don't last beyond January. Forty per cent of dieters quit within a week.

We all have bad habits - whether it's a weakness for junk food, a smartphone addiction or a lack of exercise. We start the new year with good intentions to change. But change is hard. So how can we kick our bad habits - and stick with it?

According to psychologist and behaviour researcher Dr Sean Young, the answer is to stop trying to change the person, and instead change the process. In Stick with It, Dr Young draws on his own research and that of other leading experts to explain how the mind often interferes with breaking bad habits, and how we can outsmart it, increasing the likelihood of making lasting change by 200 per cent.

Packed with practical exercises and real-life case studies, Stick with It shows that it is possible to control spending, stick to a diet, exercise regularly and overcome problem behaviours - forever.

Dr Sean Young is one of the world's leading experts in the field of habit-forming. He is an acclaied psychologist and the founder and Executive Director of the UCLA Center for Digital Behavior. His research involves the study of cutting-edge ways of using social media and mobile technologies to change and predict human behaviour.
