Go after the low hanging fruit.
My latest pep talk to myself,
No matter how daunting a room looks, there's always some low hanging fruit. In other words, there's always at least one thing that you instantly know is trash or you instantly know right where it goes.
And once that one obvious thing is cleared, there's usually a few more almost as obvious things. And once some of the low hanging fruit is taken care of, it's a little easier to tackle some of the other stuff.
