There are days when I wake up and don't want to move, but you must show up!

You have to do something like that to get rid of the tension, take your mind off what you are doing.

First of all, you learn to manage stress. You learn to live with stress. I mean, stress is there all the time. There’s no question about it. It’s in the morning. It’s at night. It’s at 3:00 in the morning, but you need to learn how to manage stress. Sometimes it’s more difficult than others, but you try to distract yourself. Whenever I have the chance, I like to go and have a round of golf. I have a passion for modern art. I have a passion for antique carpets, classical music. To me, these are distractions, and sometimes my wife, she think I’m obsessed with these little things, but I tell her it is my way of distracting myself from just constantly continuing about my work. But the stress is there. But sometimes, the euphoria you get from a sense of achievement in many ways compensates all the stress you had for a year or two.

Now I try to protect one hour in the morning and one in the afternoon where I turn off Slack, and I don't check email. I might read, or write in a journal, or just go for a walk. It's become one of the most important parts of my day. It's when I'm most creative, and when I hit on ideas that can take the company in new directions.

We are the richer for our difference, and poorer for our division. Through genuine debate and dialogue, through rebuilding trust in information and one another, through empathy – let us reclaim the space in between.

Recently I had the privilege of joining ex German Chancellor, Angela Merkel on a panel. I have long been in awe of her leadership, not least for her endurance. She was in power for 16 years. I once asked her how she managed it, her response was "things have changed a lot."
