Elon Musk has a lot on his plate.
The tech entrepreneur now balances his time between his two companies, Tesla and SpaceX. His jam-packed schedule sees him darting back and forth between SpaceX's LA headquarters and Tesla's base in the Bay Area.
But how does he manage to get everything done?
Well, as Inc. reported, the CEO ignores most phone calls, abstains from getting stuck dealing with emails, and sleeps around six hours every night.
What's more, Musk has a special strategy up his sleeve: He breaks his entire day into a series of five-minute slots. Musk even eats his lunch in five minutes or less, usually during a meeting.
As Stephanie Vozza writes in Fast Company, breaking a schedule into smaller increments can provide a major productivity boost. Five minutes may seem like nothing in the scheme of things, but the practice likely helps Musk stay on task throughout his busy day and ensures that none of his time goes to waste.
It also helps that the tech CEO says he is constantly trying to innovate and enhance his productivity.
"That's the single best piece of advice: Constantly think about how you could be doing things better and questioning yourself," he told Mashable in 2012.
