Practice estimating distance. Range finders are helpful, if you have time to use them. Otherwise, you’ve got to be a good judge of distance. Have someone toss out four-inch-square blocks of styrofoam or ethafoam around your practice stand at various random distances; then shoot at them. Or, shoot from various, random locations.
Practice in your hunting clothes. Practice with your face mask, if you hunt with one. You’d be amazed how much your shots can differ with and without. Also be aware of how bulky clothing could affect, or even interfere with your shooting.
Don’t forget fundamentals. Practice makes perfect, but you can also learn bad habits. Remember the mantra: pick a spot, breathe, squeeze and follow through. Squeeze the trigger on your release aid - like a gun, it should be a surprise when it goes off. And concentrate on holding your sight on target after the shot. Don’t try to look around the bow to see where you hit.
