My best job is my job now... I am a Director of several companies and enjoy an immensely varied day, every day. I have the benefit of very well trained and motivated staff and life seems perfect in every possible way.
However, just seven years ago, I was doing my worst ever job. I was cleaning vomit and sh*t out of phone boxes in Oxford. This was a horrible job that came with little or no dignity - I even had party goers p*ss in the phonebox in front of me, just for fun!! Bless them, bet If I saw them now I would be asked if I want to "Go large with that" ! haha
I did this job as I needed a vehicle to get to interviews and they provided a bar-fly infested fiesta van that got me to my interviews and, in time, set me on the path to where I now find myself.
