Sorry to be one of the doomsayers, but I don't think you can
do it. The Project Golfer series in Golf Australia was a good
read, and an indicator of how difficult it is to do what you are
trying to do.
The main reason why I don't think you can do it is due to
your age and life away from the course. Once you get old like me,
your learning capacity, and most particularly your ability to put
your lessons into practice is lessened. Literally, you are
probably too smart to completely and utterly put yourself in the
hands of your pro. The temptation will be too great to try
something all by yourself, or question the advice you are given.
You will also find it really hard to devote the time you need to
the task. Ten hours a week is harder to find than you think it
will be, particularly if during some of those hours its raining,
cold or windy.
Having said that, there are two scenarios where there is hope.
Firstly, if you hit the ball a long way, you already have the
clubhead speed, so the basics may already be in place. Secondly,
if your main weakness is your short game, that's the easiest
to practice, and maybe the potential exists for a really hot
round with three chip-ins to get to the magic par.
Anyway, now you have advertised the challenge on ISeekGolf, you
are obliged to keep us up to date.
