How do you want to begin?
You do not need to understand the whole system first. Pick what is closest to your question: start with the normal baseline, start from your situation, or go straight to a topic you already know.

Two clear routes first
Choose the route that fits first. Start with the normal baseline if you want a practical default path. Choose your situation when work, family, healthcare or safety changes the advice.
Start with the normal baseline
Get the biggest gains first with a calm, practical route that is enough for most people.
Start from your situation
Use this when work, family, healthcare, safety or responsibility makes another route more sensible.
