TLDR: Have you gone through a major career/industry change after already establishing a genuine career? I'm ideally talking about a change that required significant retraining or returning to university. If so, what was your experience? I want to know if I should do it too.
My personal background, for anyone bored and wanting to weigh in.
28yo Male. Engineer (civil and enviro) degree, landed in a fairly lucrative mining career for the past 5 years. Never lived anywhere more than 5 years so want to give 'normal' life a crack.
Genuinely considering pursuing a slight career change into less stressful council style engineering to enable a more settled down lifestyle for family plans. To give context, my hours would go from ~55hour weeks to 38 hours weeks, pay would drop by about the same ratio.
Given I'm already planning to throw away my current career progression, the thought of a more drastic change is eating away at me. I've always felt unfulfilled in engineering and have had a lifelong passion for psychology. Eg spending endless hours reading and researching. Anecdotally I seem to always be the go-to guy among various friend groups to disclosure issues and seek personal help from, and I absolutely love hearing people stories and helping them assess and beat their challenges.
Along with this I always had a burning interest in medicine while in school but was scared off by the difficulty reputation, now I'm dating and friends with few doctors/psychiatrists and I'm regretfully seeing just how achievable it would have been, so the mid(quarter)life crisis is hitting hard.
On the one hand, clinical psychology seems the best match on paper, however, its grossly over saturated and difficult to get placement for accreditation, including lots of luck and around 6-8 years to get started. The ludicrous luck and years requirements actually mean that a medical degree followed by a psychiatry specialisation would somehow be quicker, but, obviously caries more academic and financial challenges.
So my final decision to make is do I:
A. Stay in my general industry but move to a more relaxed role with lower hours, allowing me to get satisfaction from extra curricular activities.
B. Stay in my exact industry and make more money, but at the expense of stress, time at home, and time for hobbies.
C. Start from scratch and return to uni, meaning I will be beginning the new career in my mid 30s with all my mining savings likely eroded.
None of us can really tell you what to do, but Civil Engineering is so broad that it lays the foundations of Engineering to allow you to pivot to different niches and specialities by adapting your knowledge and base skillset.
I would suggest exploring potential opportunities to build on your current experience and see what works better for you. This can range from council as you mentioned to consultants to construction contractors to client-side etc and industries from buildings to railway to infrastructure planning to airports to bridges etc. All wholly different experiences with similar basics.
Maybe consider doing a TAFE course for Psychology/medical sciences in parallel spare time and see how that goes. If it ignites a fire in you afterwards then progress that space.
Also: Consider setting a framework in place to obtain Chartered Engineer status. This may give you something to work towards and look forward to with a sense of accomplishment (plus the promotion and pay increase that comes with it).
