Explaining the picture

So, this picture I posted of me is pretty much how I always feel. Being a mom does that to you. You are always tired. And yet, I love what I do. I love my boys! I love being at home with my boys! It is so rewarding. I want to know how it is that we as moms can keep pushing on. How, even though we are tired, and worn out, and many days just plane frustrated with everything, we keep wanting and asking for more?
My husband especially cannot understand this. When I tell him there are more children that are supposed to be in our family he says, "We are busy enough with the one's that we have". He knows that I am always right in these matters and yet he will not submit to the idea just yet. He just doesn't see how we will manage. He doesn't understand that as a mom, it doesn't matter. We keep pushing and running to manage everything.
Now I tell him that I want to home school our oldest that is struggling greatly in school. He is only in Kindergarten. He has ADHD and is hard to manage at home as it is. But something inside tells me it is the right thing to do for him. So, I am researching it and finding that I really like the idea. One more thing to add to the plate and yet it is exciting to me to know that I will be able to spend more time with him. That I will be the one who is truly molding him into what I want him to be and what I think is important for him to learn. I will be able to help him in a way that no body else can!
So the days of being tired will drag on. Adding two more busy yet wonderful things to my plate. There seems to be no end in sight, but I would not have it any other way!
