The way I try to jumpstart this for myself is to take a picture of the place I need to clean. It gives me a fresh perspective so it's easier for me to identify what needs to happen. Secondary benefit is it's easier to make a before and after comparison, for that extra hit of dopamine.
I did that once and the before/after dopamine is nice. But the downside is that looking back at the after photo and realising that it looks like shit again after 10 weeks is even more depressing.
