There are lots of right things to do in a golf swing. If your swing isn’t working, you’re missing a few. Or maybe just one that would fix everything. So you go looking for fixes on YouTube or in books.
The problem is that you really don’t know what it is that will fix your swing. Trying out this or that can easily lead you in the wrong direction, or distract your attention away from what you need to change to get to the promised land.
That is why you should get a lesson. The pro can see right away what it is you need to change, and thereby save you from going down one dead end after another.
Winter is a good time to get that lesson. You can spend a few months working on it so that when the season opens in the spring, you will be ready.
