Three constraints before I build anything

To ensure creativity and focus, I use three constraints: a one pager that captures my north star, a core piece of technology that supports my product, and a defining constraint that gives my product identity. If a project fails to meet any of these constraints, I don't build it, as it will likely result in a complex, bloated, or unidentifiable product.
