I focus on one little thing at a time. That is how I improve my healthy lifestyle. Once I do the problem solving to make that little change I give it some time until the change is incorporated into my life on 'auto pilot'. This way, I don't have to think about it or work at it. I have just become a person with that little thing in my life. Soon I will be a person with a shopping list that has less HFCS. Then I will have a kitchen with less HFCS in it. And I will be ready to move on to the next thing in my lifestyle that I want to tweak.
OK, that part about problem solving 'one little thing at a time' until it runs on auto pilot ... and then moving on to the next improvement ... THAT is life changing! That is the way you comfortably build your healthy lifestyle!
