You're totally misunderstanding what he's saying. It's that these people are kidding themselves and effectively completely wasting their own time. Instead of working 9-5 being productive 90% of the time, they're working 9-11, but during 9-5 they're 30% productive then make up for it by doing a heroic effort in the evening. If they'd have just focused earlier, they'd be at the cinema with their friends. I've been in that scenario, getting nothing done during the day then working hard at home at night. It creeps up on you, to begin with you're working all 10 or 12 hours. By the end of it, you're not.
