I like living in my head because in there, everyone is kind and innocent. Once you start integrating yourself into the world, you realize that people are nasty, mean creatures. They're worse than zombies. People try to crush your soul and destroy your happiness, but zombies just want to have a little nibble of your brain.
When we think we're multitasking we're actually multiswitching. That is what the brain is very good at doing - quickly diverting its attention from one place to the next. We think we're being productive. We are, indeed, being busy. But in reality we're simply giving ourselves extra work.
