Ask HN: How do you visualise your business?

I work two days a week on my own business by myself. My main income is a SaaS product and I have a number of other projects including websites and apps (apis) which contribute to my income. The income currently fills the gap of being an employee 3 days a week.

I would be interested to hear about how folk visualise their business. What do you go back to remind yourself of what your business is about? I don't think I'm talking about project management. The analogy of a map, rather than directions on how to get there, comes to mind.
