User stories are a business analyst tool that are also effective for creating a designed life.
A user story is a sentence with the following form.
I want to do something to get an outcome
To use user stories in your life, start by identifying the outcomes you want in life.
Then, based on those outcomes, figure out what you can do to create those outcomes. The actions and outcomes can then be used to create a set of user stories.
The user stories then become the requirements for how to live your life in order to have the outcomes you want.
