That was an interesting - and funny - story. A good read : )
One thing for the OP to note: working in 3D doesn't necessarily mean movie VFX - far from it.
From everything I've read, including Dave's post above, working in VFX is just as 'bad' in terms of working expectations / conditions as working in advertising - if not more so.
There are other niche areas for 3D - less popular, less glamorous, but maybe more viable as a long term career option: visualization for: architecture, scientific / medical, industrial, defence / military, etc. Realtime 3D for training and system simulations - and more. They require you to develop more specialist skills / knowledge, but might offer you another route to explore.
