Your view of the world is a little too rosy
If it is that easy to get money by playing the markets and property I would be retired by now.
For example, according to this:
http://findre.com.au/index_returns.html
annual nominal returns on stock markets and property is approximately 10%..
let's say you are GOOD and get about 15%. Factoring out inflation thats about 12% real.
assuming you want an income of 80000 you would need about 700K capital to start with
then you will need another 100-200 for the bad times.
That is all on top of your house and other assets which doesn't generate income.
so before you even start you will need to be a millionaire.
assuming a 60k income.. you can save (a liberal estimate) 40k a year.
that will mean you can't start until 15-20 years later
all this being the lucky scenario... with some bad luck it would be worse
-----------------------------------------------------------------
Ofcourse you could try derivatives (buying options or futures for example)..... but that's quite risky..
you will need to be lucky for the first 7-10 years with high risk investments

You are more likely to make big bucks young being an engineer.
