Our behaviors wear grooves in our minds that make it easier to follow and harder to change. Care begets care, neglect begets neglect, and changing is difficult and must come from within.
It has to come from within. A person has to decide to change. That realization can come from a shock or external motivation but that wears off pretty quickly and people can always rationalize things. I’ve lost 8 kgs since september and have gone from over weight to normal weight. I’ve tried that many times over the past several years without any success. I honestly don’t know why I stuck with it this time. I did develop a personal strategy that helped, but it takes determination more than anything.
