Imagine you are 25 been working for a bit after uni and have some money saved. Imagine you had saved $30K would you pump it into a postgraduate specialist degree or would you use it as a deposit on an IP?
The specialist postgrad degree might bring in the $200K+ a year in income (with significant stress on top as Alex correctly points out).
Am doing the above now - except getting work to pay for a postgrad in accounting and a CFA, spending the 30k on a house. (I do have a fiance though who earns a decent amount, although spends a lot of it as well)
