Which of the following is an internal influence on your health?

Your Values, would be your view and motivation and how your brain would justify all your actions.
External Influences are family, friends and environment.

Note: Intrinsic motivation is different to motivation but it could be beneficial e.g. exercise, you view it as horrible so you will get no where but if you view it as healthy and good for you and your reward is weight loss (or a protein drink or whatever) you will be motivated to do it.
