Tom, it takes a bigger person to take initiative and choose a different path than other kids who waste their time on facebook, twitter, instagram, etc. Like others have said you are on your way to be a successful person, I wish I was wiser when I was your age. I second what Benny said about studying English and Maths, especially Maths, it will definitely improve your analytical skills and even though I only been in the property industry for 2 years, often you need analytical skills whenever you face unsuspected situations and "between a rock and a hard place" types of situation. Finally, familiarise your self with good property sites such as: http://www.realestate.com.au/buy, http://www.rent.com.au/, http://properties.mitula.com.au/, to get your head around different types of property, their locations, prices, etc.

You'll be right, mate.

Cheers,
