I will lose weight... I won't overeat... I want to be skinny, healthy, look and feel my best, be fit, in shape, have good eating habits and learn to not turn to food to deal with other stressors.
The will and won't part are the parts that push pull against your fears and instincts and the want part is our free will, the gift of discernment and choice we are lucky enough to be born with.
What fears are festering that work against my won't? Fear of not having enough, fear of missing out on taste, fear of doing something differently? We are only born with two fears - fear of falling and fear of loud noises. Every other fear is learned and purely circumstantial.
What instincts are pushing my will to the limit? The instinct to accumulate fat in case of famine? The instinct to eat while there is plenty? Problem is there's always plenty.
And what do I really want that can override the fears and instincts that take over logical action?? ... After all I actually get to choose!
I'm working on actively choosing.
