Put energizing music on. First get all the trash out. Second, put all laundry on one pile or in the hamper. Third, put like items with like items in multiple piles. Fourth, go through each pile and make another pile of stuff you want to say goodbye to. Get it out of your home. Organize the things you're keeping. Sweep the floor. Wipe down surfaces. Hang up clothes. Things should be cleaner now. This is my idea. Someone else may suggest something else.
Buckle down, and just pick it up...listen to a song...first thing,second thing,third thing..sounds boring but it will get clean. its only bad when you will sit around it and refuse to move. That's WAY worse!
