My wife is like you, she sees everything she has to do as a huge "lump" of work and gets overwhelmed and distracted trying to make progress on everything at once. She's also ADHD which means she very easily gets distracted by something, which then leads to hyperfocus on that seemingly unproductive thing.

I see the kitchen and I think "this is going to make my back and legs hurt so much, I'm going to rest a bit before tackling it." Then I get distracted with reddit or HN or whatever, and suddenly it's the next morning and I have to work again.
