Simplicity is about subtracting the obvious and adding the meaningful. In that definition are the two Simplicity Paths: tearing down and building up.
Tear down and Build up
Most (all?) of the time, you’ll need both paths, working together. Simplicity is a give-and-take. As you remove what you don’t need, add back the meaningful stuff.
The core is my favorite part. It’s like a wall awaiting paint. I push myself hardest to tear down, because only then can I experience the project from the core, building out.
