## What is Enera?

Enera — The 3×8 Energy System

Enera is built around the 3×8 energy structure.

Your day is divided into three essential investments.

Yield

Work that produces short-term results, such as delivery, operations, communication, or sales.

Equity

Efforts that create long-term compounding value.

Examples include product development, learning, writing, and physical training such as exercise or workouts.

Recovery

Activities that restore your energy, such as sleep and rest.

This structure helps balance short-term results, long-term growth, and energy restoration.

Momentum System

Enera includes a simple momentum rule.

If you complete 30 minutes of Equity work in a day, your momentum becomes:

Momentum = 100

Equity activities can include:

product building
learning
creative work
and exercise

This encourages consistent investment in long-term growth.
