Is it worth exercising?

I have been trying to be really good and get some exercise in EVERYDAY except for Sundays.  I have been doing really good this last couple weeks.  Then yesterday I was wondering if it is even worth it....

I put Samantha down for her nap, I got my exercise grubs on... put in my DVD that I have been working with.  I put a episode of Charlie and Lola on TV for Amber down stairs and I get to my workout. 

I hear lots of funny noises downstairs... sounds like a chair fell or a stool maybe...  I keep working out listening for signs of distress from Amber.  She is quiet, I keep on sweating...

Amber comes up to help me do my "exercise game" as she calls it.  She always has to take my weights and wants to use them.  I finish up, and am just doing the stretches and notice Amber has something yucky in her hair. 

I ask her what is in her hair.  She tells me nothing.  I tell her she has something in her hair and ask if it is yogurt (but then I remember we don't have any yogurt right now).  She replies, "oh, it's butter, I was making cinnamon toast, and it is really good!"  I ponder that for the rest of my stretches and remember I don't have bread and sent the girls to school with money to buy school lunches because of it. 

I turn off my DVD, I go downstairs. 

This is what I find....

This would be our little dish of cinnamon and sugar mixture for cinnamon toast, and ALL of the butter in the dish.  Not pictured is the butter covered drawer handles, oven handle, stool coated in a nice greasy layer of butter. 

Amber went on to tell me how she was mixing up the cinnamon for toast... and how good it was. 

She also during my workout managed to spread the cat food all over... on the couches, in the bathroom, in the entry way, all over the kitchen floor, the dinning room floor, and the family room carpet.  Last night when I was getting Samantha back into her pajamas, she had cat food in one foot of them. 

Amber also dumped out Lindsey's money (all coins) and spread it around on the carpet too.  That was the least of the messes.  I then wonder, is this all worth exercising for?
