Question: how long does it take to make a change in your life?
Answer: The reality is that it usually takes much longer than Maxwell Maltz's misinterpreted 21 days to change or form a new habit. A 2009 study by Phillippa Lally, a health psychology researcher at UCL, entitled 'How long does it take to form a habit', found that on average it takes 66 days for a habit to become ingrained.
