Best Ball, Solo
Why this drill
Worst ball's kind twin: two balls from every position, play the better. Best ball shows you the golfer you're becoming — the score your good swings already add up to — and builds the pattern-memory of hitting from good positions that bogey golf rarely provides.
Setup
An empty course at a quiet hour, two balls, normal bag. Nine holes.
The drill
Two balls from every spot, play on from the better — better drive, better approach, better chip, and putts too: two tries, take the make. Score the nine. Expect five to eight strokes under your usual; that number is not a fantasy, it's a preview, and chasing it is the drill's engine. Note where the two balls were both poor — those spots are immune to second chances and first in line for block practice. Alternate best-ball and worst-ball weeks: one builds belief, the other builds honesty, and a golfer needs both.
One thought to take with you
Watch what the good version scores — then practice toward the preview.
