Bob Rotella the mind guru and sports psychologist to a good number of the players on the PGA tour says “Acceptance is the last step in a sound routine.”
You hit the shot yourself, so at some level you have to own up to it. If you don’t, that means that you are giving circumstances control over the outcome instead of taking control yourself. If you are still thinking about something that happened in the past, you can’t fully be focused on the present.
Changing a golf swing or a business practice or your life means aligning yourself correctly and working on the right things for a long enough time to start seeing results. There is no magic pill that can change an inconsistent swing into a consistent one. It often takes as long to dig yourself out of a mess as it took to get yourself in it.
You must do the self assessment to realize that where you are is not where you want to be. Often that is something that is hard for an individual to do and that is where a good coach can come in.
It is the job of your coach to help hold the mirror up to you so you can better see what is not so visible from the inside looking out. If you don’t have a coach you may start with your spouse. No one knows you better, cares about you more and is more concerned about your future than they are.
Beyond that, getting a professional coach that knows your industry and knows you can really be that boost that you need to set you on the path to winning in 2019.
