Quoting The (super kinky) Master:" I know the title sucks but I couldn't think of a better one. Do you think that if someones does really ... [snip!] ... the same position im in now by doing a computer degree (igot in via previous experience). Is this the common way of thinking?"
I think that way of thinking is common ESPECIALLY FOR PARENTS.
I think most parents want "the most" for their kids. Usually that involves a path in life that provides for as many good options as possible. Typically, the more education you have the more good options you have. BUT, that is how it usually is. There are always exceptions.... and i dont know how education and career opportunity is in Australia.
Here in the US, most thoughtdul, smart parents want their children to have at least the same education level as they have themselves. Many want their kids to achieve a higher education level.
If my brother or I hadnt finished college, my parents would have had a very difficult time with it.
If my LO doesnt want to finish college, we will have a difficult time with that issue, as well.
I assume your parents will be satisfied if they know that what you are doing has a rock-solid chance that you will be secure in your job, have good earnings and do something they think is worthy of respect. I assume if you show them that they will have something to brag about it a couple of years they will feel better about your decision.
Here is some unsolicited advice:
Think about your short-range and long-term career plan and be able to "map it out." Then, ask them to take their "parent hats" off and put on their "friend hat, show them "the map" and askthem to be supportive of the decision. From what i have seen you write on other threads, it seems like you are making good, practical decsions about your career. Perhaps they need to be reminded that you are an adult and making good adult decision.
