Instead of saying, "I am"...try - "I have"; for instance - instead of saying, "I am fat" (ugh there goes the 'f' word again), try saying, " I have fat".
I may have fat, but I am going to work hard to get rid of it!
H - Hydrate (drink plenty of water daily)
A - Attitude makes the difference
V - View things in a positive way
E - Eat well
