Bob,
In your situation with the beer, it seems that you had to go cold turkey with it when you realized the health repercussions for you and so this forced you to change that structure.
But what about things that we don't have to change such as settling for mediocrity, being complacent, etc.? This is the struggle I seem to be facing at this point.
Of course, I shouldn't be so quick to say that realizing a health repercussion makes it easy to change your structure just because you have to so that your health isn't compromised. For example, my father had quadruple by-pass surgery a little over a year ago. The doctor was very clear with him that if he kept smoking and eating bad, he'd be right back on the operating table. Regardless, my father has gone right back to eating unhealthy and smoking as he did before. The health repercussions were not enough for him to autmomatically change his structure. Foruntately for you, you place more value on your good health and your desire to NOT have vertigo than having the pints of Guiness with the guys. You realized that you could raise a glass of a non-alcholic beverage just as easy in a toast and you wouldn't be compromising your health. Good job on that structure. Now, how do we change the structures that are keeping us all from becoming billionaires? :O)
