[commanda]

The OP sounds like an angry curmudgeon. He/she can't cut someone some slack if they're running a few minutes late? I'm glad I've never had to take a meeting with this person. This isn't about whether or not someone is disciplined enough to get enough sleep - this is about OP's rigid inflexibility. Things happen - your child has a tantrum at breakfast and spills something on you, your car has a flat, your cat dies. If life's inconveniences are too much for OP, he/she should consider working solo.
