My message to younger people starting in the workforce is be prepared for change and have the desire to re-invent yourself when needed. This also applies at any age as evidenced by the success stories in previous posts.
No matter what your political beliefs are, living in Australia provides the opportunity to succeed.
If you are of average intelligence, possess reasonable health and have the motivation to do it you can. The key is accepting CHANGE, whether that be for study, re-location, different hours, taking on risk or whatever it takes. The alternative is to do nothing and complain about it. Then nothing will surely change.
