As per the title, what job have you had (past or present) that has been your most favourite job? By this I mean you looked forward to going to work, you enjoyed the work and overall you felt very happy working in the job.
I worked at the movies when I was in school and at uni and have to say that was probably the job that I most enjoyed when I look back on it, even despite the pay being very low compared to what I earn now.
P.I.M.P.
