The most dangerous way to lose time is not to spend it having fun, but to spend it doing fake work. When you spend time having fun, you know you're being self-indulgent. Alarms start to go off fairly quickly. If I woke up one morning and sat down on the sofa and watched TV all day, I'd feel like something was terribly wrong.... But the same alarms don't go off on the days when I get nothing done, because I'm doing stuff that seems, superficially, like real work.
