No, I feel that Sunday is the day of rest I start my week with, then I do some work, and finally I rest again: in that way my day is a microcosm of my week (and one might think that in a more primitive society my year would be a macrocosm, as I did more work spring-summer than during the winter).
I personally detest calendars which display Monday as the first day of the week, and am genuinely curious why ISO chose that.
Born on a Monday,
Christened on Tuesday,
Married on Wednesday,
Took ill on Thursday,
Grew worse on Friday,
Died on Saturday,
Buried on Sunday,
That was the end,

There's a bug in cal -- the man page says "-M" makes the week start on Monday, but my version doesn't accepthe argument.
I find it quite confusing when calendars mess this up. I once booked a flight on the wrong day, because I somehow switched to the American localization of the airline's website part-way through the booking process.
You might be interested to know that in Israel the work week starts on Sunday, not Monday. Friday and Saturday are the weekend.
That might just be a factoid, except that the Jewish Sabbath was the origin of the weekend concept. It changed in countries with a strong Christian influence so that Monday because the first day.
It never changed in the US because the Jewish workweek had a stronger influence there than the Christian one.
> I personally detest calendars which display Sunday as the first day of the week
And I personally find calendars that start on Monday quite bizarre since it's obviously incorrect historically.
I think ISO chose it because there was considerable difference between countries as to what the first day of the week in usual calendar presentation was when ISO 8601 was being considered, they needed something consistent, and it just happened to shake out to Monday.
Because ISO is all about business, and Monday is the start of the business/banking etc week.
