Some things to know and practice: First, and most important search and ask around about a respected golf instructor in your area, and get them to give you information on their program prior to starting an instructional series. You don't want someone giving you advice who is not qualified, and can impart poor information that can create bad habits.
Secondly, You learn to play golf by feel, not mechanics alone. Too much detail is confusing. You cannot think your way through a golf swing. You feel your way!
Finally, short practice sessions regularly are better than one long period. Practice, and good repetition, will teach your muscles to learn to feel - creating your own internal dialog from within that you, and only you, can describe to yourself.
Ultimately, start out with a plan, and take your time because as the saying goes "You must learn to crawl before you can walk."
