There are many jobs I would consider my dream job. I've said since 7th grade that there are far too many things I enjoy doing to have just one career.
That said, aside from the overwhelming quantity of work, I've had one of my ideal jobs for the last 2+ years. I'm in a teaching role, helping graduates pass a licensing exam. I love the field of study. I'd be a perpetual student if I could, and since the field encompasses 15 individual subjects (in my state - a dozen or so more for the handful of students who seek licensing in another state), I pretty much am a perpetual student. I have hard-working students who are motivated to succeed - and at least once a day someone tells me they appreciate what I do. Twice a year I see my students succeed at rates higher than before I arrived here. I seem to be effective at what I do - and I've never been in a job where those I was directly helping appreciated it and articulated it so frequently and clearly. (One student ranked me 15 on a scale of 1 to 10.)
I arrive at work smiling every day.
But I'd also enjoy being a computer programmer, a civil rights attorney, a seamstress, a chef, a photographer, a mathematician. . . . you get the picture.
