Healthy Eating or Exercise?

It seems like I either exercise or I eat healthy. I can't seem to do both with any sort of consistency. Take today for example. I had a small bowl of cereal and a 50 calorie cappuccino for breakfast. Good so far. Then I had a banana for a snack. Still good. I did my exercise this morning. Check mark for that. Then at lunch I had a grilled chicken wrap with lettuce, cheese and sweet chili sauce. That was okay. Not terrible. Then my son grabbed a package of Little Debbie Zebra Cakes and wanted to open them. Of course there are two in a package, so I ate one. Bad girl! Okay, I can do better from this point on right? Not so much. So then I pick up my daughter from school and my fiance calls me and needs me to come over to his workplace so we can take care of some issue that we have with the car we had in the shop being worked on. So, the kids are hungry by now, and I stop to get gas and get them some snacks in the convenience store. They get white cheddar popcorn and juices. I got a diet soda. But then I saw it...Buffalo Blue Cheese Doritos...OMG. Could not resist. I got them and I ate them all. Then we get home and I have to throw together a super fast dinner. We had chicken nuggets, french fries and macaroni & cheese. At least the nuggets and fries were baked, but still. Oh, and I put my nuggets in a wrap and added sweet chili sauce. So many calories by adding that to it. So, I got in my exercise, but didn't eat all that healthy. I also seem to start the day out well. I eat a normal breakfast and snack and get in my exercise, and then it goes to pot. But there is always tomorrow to try again, right? How many times do you have to start over on a new habit to get it right? The world may never know....
