These are all good suggestions none of them really cover it.

Some around-the-home examples:

• Get robot vacuum, no more vacuuming your house.

• Lay stone around your borders, no more weeding.

• Install hydrophobic glass windows, no more window cleaning.

• Get dishwasher, no more washing dishes (this is partial as you still have to load the thing).

• Get a car, no more carrying groceries.

• Get washing machine, no more handwashing bedding.

Basically where you make an investment of time or money, to remove a time sink from your life whilst still keeping the benefit of the thing.

I feel like most people would be 5x happier if they did more of this, but how to articulate it?

You could actually make an algorithm to calculate Time Returned on Time Invested and then rank all the opportunities in your life to create more time for yourself.

Do I need to write a book? 🤣
