Trying to find motivation..

I have a 12 month old little lady & I'm currently pregnant with her little sister, we couldn't be more happy! But I'm finding it so hard to get motivated to get their room ready for when the little one gets here at the end of June/ early July. I still have so many clothes that others gave to us that I never used or didn't like that I still have to go through & get rid of! This momma has no energy or motivation to get anything done! I have just over 14 weeks to go so I'm slowly running out of time cause I know it's gonna go quick! Any advice on how to get a little energy or little motivation to get things done soon? I'm gonna try little by little, so hopefully my motivation shows up soon lol
