A scaffold

Building anything of substance, taller than you can build on your own, you need a scaffold.
Sure, with enough time and energy you can dig the trenches on your own, you can lay the footings and build the foundations, you can raise the walls to head hight. Get a few friends, with like minds and a common idea in their heads, life will go a little quicker.
When you hit your natural limit though, when you need to leave the ground and reach higher than you can stretch, you need that scaffolding. Something, a framework, that lets you build higher, gives you access, keep you safe.
It’s a statement of intent.
It’s a guide, based on your current idea of what happens next and what’s supposed to happen after that.
With it, you can keep on going. Without it, you’re confined to the ground.
Skippy strategy: Organisation, structure, focus, discipline.
