The best job in the world is the one that challenges you, makes you feel fulfilled, and gives you something to look forward to every day. Every job has down days, and moments where you just don't feel like doing it, but if you can find a job that meets these three things more often than not, you've got it made. This will be different for every person obviously - for me, it's writing, for others office jobs, being a stay at home parent, or working a few part time jobs. And that's the beauty of it - you don't have to fit a preconceived notion to have the best job in the world!
