Writing beliefs - best practices?

Are there any particular best practice people have adopted (outside the advice given in the book) for defining beliefs? I ask, because I see occasion references to things like “my big picture belief” or similar. I also sometimes see beliefs crafted in a fairly formal way, such as Overarching philosophy, therefore I will specific action.

Is there additional advice on writing beliefs to be found somewhere outside the core rules? I’m particularly interested in the split between characterization, short term goals, and more overarching statements of belief.

Check this out.

Thank you, that’s exactly the sort of thing I was looking for!
