Specifically, a strong capacity to hit successful chip and pitch shots from around the green. There's additionally a lingering impact of having a decent short game.

1. Effective Chip and Pitch Shots to Increase your
Confidence Level
In case you haven't noticed by now, the fastest way to lower scores comes
from having a tidy short game, specifically, a strong ability to hit effective
chip and pitch shots from around the green. There's also a residual effect
from having a good short game. When you chip well, you don't feel
pressured to hit every green, which ironically, leads to hitting more greens!
Let's look at a handful of short shots that will help you gain confidence and
shoot lower scores.
BETTER CHIPPING
I'll tell you this, I've shot some pretty decent scores in my day, and some of
them I did while hitting less than 50% of the greens. Sometimes, I've even
been well below that 50% number and still managed to salvage some
decent scores.
The key is having good technique. If you look at the sequence on the
opposite page, you can see the classic "chicken wing" position post-
impact. This happens when the mind and body both feel the need to lift the
ball up, instead of allowing the loft of the wedge to do the work on its
own. In this photo, check out how low the clubhead is post-impact.

2. See how low it is? That's what you want for solid chipping contact. There's
no lifting or pulling up with the hands—not ever, actually.
TRY THIS
You've maybe tried some unorthodox putting grips to help cure the putting
yips, but have you ever tried one with your chips? The key to better
chipping is quiet hands and wrists, and using an unusual putting grip like
the one you see here actually can help you. Grip the club with your normal
left-hand grip, and then put your right hand to the side and tuck the grip
into the fold of the thumb and index finger. You can't get cutesy with the
hands using this grip, and you'll quickly feel what a proper chip stroke
feels like.
