new year, old problems

It's been a long time since i did maths, but i do remember enough to note that, at least for me, work experience is inversely proportional to the demands of the job. In other words, as each new year has passed and i've correspondingly become more senior, there just end up being more things to do (and more difficult things, at that), and the result is that i end up as tired as i was the previous year. Not complaining though, of course. Just observing..
