How do you motivate yourself??

I've recently decided to be a stay at home mom, which I love, but I'm having a ridiculously difficult time motivating myself off the couch once I sit down for a break. I keep thinking to myself as soon as nap time is over I'll get up and do something productive but it's just not happening. I keep letting myself get sucked into stupid shows on Netflix that I've watched before. (my daughter is in no way being neglected by the way) How do you motivate yourself to get more out of your day?
