I come from the generation who were taught never to throw things out. I like the idea of hanging on to things and repairing items rather than discarding them. It’s not a question of money, more to do with guarding resources and not being wasteful. My children laugh at me when I sit darning a pair of socks.

And what happens for me is that I make a pot of beans on Sunday. And I also make some greens with chard, whatever I have available. And when I come to cook a meal or even to make myself breakfast, I may warm up some of those beans. I put a little tortilla right on the fire. I fill it up with the beans, maybe a little hot pepper, and I eat it. And that takes me exactly two minutes, three minutes, maybe. But it’s knowing how to cook. Those basic things have been taken away from us.

Keeping all devices aside 1 hour before sleep, stopping all work chats at Zerodha unless critical after 6pm, and spending time doing what is most relaxing just before sleep (spending time with my son & hobbies) and on weekends has helped me the most with sleep.

I don’t lead by force, I lead by example. And if I can, set a good example. If I can set an example to my staff and my group, by being punctual, I come to work every morning, walk onto the hospital floor within two or three minutes of the same time every day, and they can depend upon it.

Do restrict your browsing to a few websites a day. Don’t go near the online bookies – unless it’s research. […] Do not search amazon.co.uk for the book you haven’t written yet.

Do, occasionally, give in to temptation. Wash the kitchen floor, hang out the washing. It’s research.
