It's often commented that you need a huge amount of patience to teach golf!  I always reply that actually if you simply understand how difficult  this game is then you should be well positioned to help people improve.  I would suggest the client is the person who requires the patience and also a realistic expectation to what they can achieve in a certain time scale.

No one ever masters golf,  so don't go into the game with that intension, otherwise your in for a long ride and one that won't be that enjoyable!  Set realistic goals and take into consideration your family and work committments, just how much time do you have to work on your game?  Talk through with your Pro what it is you want to achieve and he will help you plan a suitable practise schedule etc.

If your expectation and your teachers are aligned correctly, then we all know what is expected and I guarantee you, you'll enjoy the ride and achieve great success in a much shorter period of time.
