Many people take up golf and then give up because they don't play enough and practice what they have been taught . Get yourself some lessons , get them off the assistant pro at any club who should be very keen . Then do what they tell you , sounds silly but what they tell you is what you should be doing , many players don't do what they have been taught as they generally get worse initially and as they don't practice they go back to what they were doing before they had the lesson . It is the most difficult game to play and still struggles to attract new players .
Watch other good players very closely , the grip is the most important part , getting that right is the first thing to crack , getting it wrong means the rest of the movements you do will not work correctly .
I know a bit about this game having been under 5 hcp for 35 years (15 - 50) and have been involved in the coaching of several players who have played for England .
The really important thing is to ENJOY IT .
Lastly learn the "Ball flight laws" Google it , see how they effect the flight of the ball , it will help greatly .To quote them to the professional teaching you will seriously impress them and show them you are serious . There are 5 , don't listen to the "New" rubbish about NINE , the PGA Coaching manual quotes 5 , who is right , i think the PGA might know a bit about it
( PATH OF THE SWING… FACE POSITION AT IMPACT… SPEED … CENTEREDNESSS (indicating that balls fly differently when struck on the face in places other than the center) … and ANGLE OF APPROACH OR ANGLE OF ATTACK )
