My biggest motivator at the moment, apart from taking care of my family, is property. I'm absolutely obsessed with it to the extent I spent ~1hr a day on rightmove fantasising about owning properties I can't (yet!) afford.
I can't decide whether this means my passion is property and that's where I should work, or if it means I need to work harder in my current career (finance business partner / accountancy) to afford these houses.
Either way, I'm fairly comfy in a big company with good opportunities and some exciting changes ahead in the industry I work in (energy).
I always want more though, but not such that it impacts the time I get to spend with my young family. Perhaps when the children are older, I'll give my life to a bank in Birmingham to afford that dream home.
