I really regret doing half of a commerce degree, getting a job offered and quitting University. I went on to have a career in Telco and Energy companies mostly working in designing software and technical writing.
As you age you realise your regrets, I think VERY few have NO regrets. For me it would have been not figuring out what I want to do with my life earlier on.
Anyway I would really like to work more in the hardware design in ICT not the software itself, perhaps cellphones, perhaps routers, perhaps notebooks, I dont know. I imagine the field is small so Id have to keep my options open for other industries. But basically designing products.
My ultimate would be to work for Triumph helping design Motocycles, of course with a focus on UX with that having been part of my software design work.
I think if I could go back I would have studied Architecture or Naval Architecture.
But is it realistic. Its a 4 year degree. id be a 50yo broke graduate. Perhaps it is just too much of a dream, sometimes we need to be realistic instead of destroying ourselves.
