Strength is energetic capacity, not personality
A strong Day Master is not necessarily confident, and a weak Day Master is not necessarily timid. Strength describes how much seasonal support, root, companion energy, and resource energy the self receives within the chart.
The month branch is the first reference point because season determines elemental climate. The rest of the chart then shows whether the self is supported, drained, pressured, or allowed to flow.
Useful elements come from balance
A missing element is not automatically useful. A chart that is already cold and wet may not benefit from more water; a chart that is dry and hot may need moisture or regulation. The useful element is the one that improves the whole system.
In practice, Day Master strength becomes a strategy guide: whether to build support, accept structure, express more, manage resources, or reduce overextension.
