The most incompetent person in the world is probably ME !!
When I left school the head teacher told my parents I had brains, but no sense. Over the next 30 years, I proved him right. I had over 40 jobs in 30 years, and in virtually every job I was totally incompetent, and was either laid off, fired, or let go because of a change in organisation, reduction in funding, etc etc.
In addition to having no sense, I was a hard worker, always punctual, etc. Some supervisors tried to help, but my incompetence always won in the end.
Then, I got lucky. I was hired by a large organisation, which had the well-deserved reputation of being the sloppiest company in the country. This is the kind of company where, if an employee
a) shows up
b) on time
c) sober and not hungover
and
d) ready to work
then the company declares him employee of the month.
It was wonderful, and quite well paid too. After 10 years of well-paid idleness, I achieved nirvana... I was offered early retirement, with a partial, but adequate, pension.
