Chip or not to chip??

I did really good for breakfast...I had my 2 ounces of yogart and about an hour after that I had my 6 ounces of whey...I finally felt up to mowing the front yard this morning, I did the backyard the other day...I am kinda trying to break it all up so it dont overwhelm me all at once...Ok, so I was fixing my sons french bread pizza and doritos for lunch, yes I snagged 1 chip...Just 1 and it was just so good...I chewed it till it couldnt be chewed anymore...But the best thing is that I was satisfied with just the one...I know I am suppose to be on mushies, and I mushed it...I really dont believe that 1 chip will do me in and I firmly believe that a person does not have to do without ever having anything like that ever again, just in big time moderation...So, I made it thru the 1 chip and left the room while he ate the rest of his lunch and decided to color my hair while I waited for him to finish up...I work in a room full of skinny scrawny girls that live out of the vending machine and dont do anything in regards to working out and they just dont gain a pound...Makes me sick, wish I had a matabolism like theirs (maybe someday)...But I know that I can never live like I have in the past...I still havent gotten into working out yet, but have been doing alot of things around the house to try to supplement for that...Maybe in an hour or so I will attempt that dreadful gazzelle that keeps looking at me and laughing!!!!:guess
