Variables (advanced)

Variables (PHS arrows, cognition, environment, motivation, perspective) are an advanced layer describing digestion, environment, and cognitive style. They come from tone/color beneath gate lines — beyond beginner type/authority work.

When to study

After living type-strategy and authority. Variables fine-tune lifestyle (how you eat, where you focus best) rather than replacing strategy.
