What motivates people to change?

People hardly ever change. That has been my experience in life and in my reading of history. Please enlighten me if I'm wrong.
We are unlikely to change our behavior unless we believe that there will be an immediate benefit to our health.Many of the motivating factors we’ve heared about involve changes that you need to make inside yourself.


Changing and helping yourself  to sustain changes can be quite useful:

• Surround yourself with supportive people who share your commitment to a healthy lifestyle.
• Keep healthy foods readily available to you.
• Establish an exercise routine with a partner.
• The unhappiness they feel at the time can be a great motivator. Anger, oddly, is an good motivator too. Having a goal that is important to you for whatever reason can motivate many people.
