# playing within yourself (margin)

*Ordinarily means:* performing at a level you can reliably sustain instead of straining past your ability

Acting on a true reading of its own reach while keeping a margin inside it, so it never acts at the wall itself.

## Emergence
**Emerges from:** [reach](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-reach.action), [self-efficacy](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-self-efficacy.calibrated), [wall](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-wall.range-end), [act](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-act.deed), [true](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-true.accurate), [read](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-read.information), [time](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-time.dimension), [keep](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-keep.maintenance), [margin](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-margin.spatial), [inside](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-inside.spatial), [action](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-action.deed), [persist](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-persist.continue), [never](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-never.temporal)

**Through:** A calibrated self-model supplies the location of the edge; the choice to stay a margin inside it turns that knowledge into reliability, trading the best single result for fewer crossings of the wall.

**Novel properties:**
- a margin chosen, not imposed
- accuracy used to set a limit on oneself
- reliability bought with unused reach

## Examples
- Golf coaches tell players under pressure to play within themselves: choose the shot they can hit reliably rather than the best shot they could possibly hit. *(sport)*
