You know, I used to think that my dream job was a job in something that I absolutely loved, and had a huge passion for. Something that would get me out of bed every day with a smile on my face because I was doing what made me happy.
Personally, I've come to the conclusion that I don't have a single dream job. To me, work is just work. It's pays bills. I could be doing a lot of different things for a career and still be pretty happy.
For me, a dream job is one that lets me live comfortably with enough leftover funds to travel and experience things outside my home town. In addition to that, a job that doesn't require me to talk my work home with me, both tasks and stress. If the job I has fits that criteria, and lets me come home to do the things I want to do on my own time - that's my dream job. A good job lets me come home to work on my dream 'hobbies'.
But if I had to pick one dream job, it'd be to do absolutely nothing but get paid 100k/year to do so. LOL.
