There's a huge difference between going shooting–what most people do–and what real training/practice should look like. Having a plan for the day and understanding which specific skills you're trying to develop and how to develop them.

The out of your comfort zone training pace, the exploratory nature, the deeper level of understanding of what's happening with you and the gun, the many mistakes, the difference between focus and awareness, the incremental improvements, the frustrations, how to measure progress, and when things are clicking how to make them consistent. This is just to name a few.

This is training/practice. And where consistency, repeatability, and true proficiency come from. If you're not improving and don't know why, it may be because you're on the wrong road, just going shooting. Listening to influencers masquerading as coaches instead of people putting in the work passing on how to succeed and how not to fail.

Learn how to train, and the improvements will come.
