Hi Sky Scrathcer,
Ever since I was a young boy I have always been exicted by aviation, its gets into your blood. I could not afford to learn to fly as a career, but in the good old days University in Australia was free. So I went toUniversity, got a degree, post graduate specialist qualifications,very busy practice, house on the beach, big income...
Lots of my colleagues in specialist medical practice also have levels of dissatisfaction, etc. So it really comes down to what you make of it. Make the most of any situation that you are in.
In this day and age, you can have more than one career. I have a busy practice, but also fly commercially on a part time basis. Too much flying I look forward to the practice, too many patients then I cannot wait to go flying.
I am lucky enough to enjoy both. One of my friends use to work for Ryanair, they have several part time pilots. There is a dentist that now works as a pilot for REX - a regional Australian Airline.
You are young and have a number of options, if you have a degree then you have it for life, always something to fall back onto. I got my PPL whilst at University, another good friend of mine learnt to fly in the Airforce flying clubs, whislt working as a medical officer.
There is a huge shortage of dentists that work in rural areas in Australia, I know some medical specialists and dentists who fly themselves out to regional areas and do clinics.
Good luck
JERR
