Possibly a little deep for this thread (just considering its not my thread), but my dream isn't a career change, its slightly higher - freedom from money. If money no longer plays a factor in my life, then I don't have to choose
one thing to do, I can do whatever I want when I want.
For me that's travel, adventure and photography (landscape, wildlife, culture). There's two ways I can achieve my goal, make enough so that I don't have to work again (I make it about £1.2m~), or failing that live cheaply enough that money no longer plays a major factor in my life, i.e. I don't spend most of my adult life paying off a mortgage. The plan for that would be to buy a nice old, cheap yacht and live as frugally as I can whilst exploring the world.
So either way hopefully within the next couple of years I'll be living my dream.. id rather be "financially responsible" and do it, but I'm prepared to make sacrifices if that's not possible within my given time frame. :)
