How can I motivate myself?

A while back I asked a question on how to clean a room. I got a bunch of useful answers. I am good at organizing but I have a hard time with motivating myself to do work except with animals. I keep procrastinating when I try to do things. I can do stuff like dust and vacuum but I can’t get stuff where it belongs. I need to know how to motivate myself but don’t know how to. Any ideas?
