A.W. Tozer, We Travel an Appointed Way, paraphrased by Joe Wood
"In a world like ours, we need to master the art and keep at the business of dismissing distractions."

I once foolishly bought a BT-99 Plus trap gun; fully adjustable everything. Spent 4 weeks adjusting and changing and shooting (poorly) while thinking about what I had just changed and what to change next frown Saw the light, gave up, and sold the thing.

Heraclitus — 'No man ever steps in the same river twice, for it's not the same river and he's not the same man' also applies to gun fitting.
