There are 5 reasons that people find the motivation to change:
1) Suffer enough, so they have to.
2) See enough, so they are inspired to.
3) Learn enough, so they want to.
4) Receive enough, so they are able to.
5) Be loved enough so they feel safe to. 

To be in control of your own health, motivation is a non negotiable. 

Warm regards,
