I think the Fat Smoker knows the same as you and I. It is not the strategy, it is the execution that is flawed.
Execution is more than knowing what to do. It involves the critical step of actually doing it – consistently, day after day after day, until done.
Jim Rohn tells us that success or failure is not due to one single cataclysmic event; failure is a couple of poor decisions repeated daily, success is a couple of good habits repeated daily.
The Fat Smoker knows the same things as you do. They know the strategy. They just take a few poor decisions every day.
