Hyperfocal distance in aerial photography: the focus point where everything from half that distance to infinity appears sharp.

Set it wrong and your foreground OR background goes soft. Set it right and the whole frame stays crisp.

Same principle in life. Pick the wrong focal point and either your present blurs or your future does.

Most people focus too close. They optimize for today's comfort and let the long view go soft. Then they wonder why their life has no definition past next week.
