Malcolm Gladwell is the guy who started the 10000 hours thing I think.
He writes interesting books. I believe he included even the "monkey
work" because it's all part of being complete in your work.

In calculating expected lifespan of equipment in daily use we use 2000
hours per year as average. That's from 40 hours per week, 50 weeks per
year, five years gets you to 10000 hours.

For someone slightly obsessed, it's possible to do 10000 in under three
years while still at school or working.

Best regards,

Bob
