It turns out, the key to his productivity is a habit anyone can adopt: punctuality.
"If you want to be more productive, then start at the start: get there on time," he wrote in a recent post on Virgin's website. "Whether it is a meeting, a flight, an appointment or a date, it's important to ensure you are there when you say you will be there. This may feel like an old-fashioned tip to give, but it has served me well for five decades in business."
Being punctual allows you to effectively manage your day, he explained in a LinkedIn post last year: "Once you get behind, it is hard to catch back up again. Being punctual doesn't mean rushing around the whole time. I always find the time to exercise — kitesurfing, tennis or cycling — and to spend time with my loved ones. It simply means organising your time effectively. "
Plus, arriving on time is basic etiquette. As Branson said, being late is "incredibly disrespectful. It doesn't matter if you're a celebrity or a carpenter, a politician or a painter, a model or a musician, we all only have 24 hours in a day, and no one's time is more important than anybody else's. "
The bottom line: Show up when you say you will. After all, as Branson wrote, "All you have in business is your reputation — so it's very important that you keep your word. "
