Do you feel like a success?

I was just reading a comment my sister left (a nice one, don't worry ;D) and it got me thinking. For those of you who are parents do you feel like a success? What is our measure of success? I think when it's all said and done and my kids grow up and move out I will hopefully feel like I did a good job. I have made the necessary sacrifices, I have lobbied for my kids, I have done the therapy and doctors and stuff that needed to be done. We do extras like the park and crafts and playing outside when I am so tired I want to sit on the couch. But why, some days do I feel like I should get a D-?

You know, those days where you put them to bed yelling. Or the day when, once the kids are asleep, you can't remember whether you held each of your babies that day and hugged them tight. Or the day where you want nothing more than to pawn your kids off on someone else, ANYONE ELSE! Those are the epic fail days for me.

I think this is just part and parcel to being a Mom. I think we are supposed to feel this way. If we all walked around feeling we were in contention for mother of the year maybe we would become complacent and take our role for granted. Maybe we have that innate guilt for a purpose. To push us. To motivate us. To get us off of our a$$es on the days when we want to sit around and do nothing. I would like to think that it's not for nothing. That I am not alone. That even when I am doing the best that I can I still feel like it isn't enough. And that feeling like that is normal. :D
