Golf is like rowing, like knitting, like learning a new language. If you start without instruction, you'll build bad habits that stay with you forever. You can row as hard as you want, but without proper technique, you’ll never get faster. Golf is the same. Effort doesn’t equal improvement unless it's guided. If you start with fundamentals and practice them intentionally, you will get good. But if you repeat the same shitty swing for 10 years with no feedback, you’ll end up exactly where you started.
