2. Listening to classical music on the radio. I used to listen to the news during dinner, but since I switched to music I feel much less stressed and much happier. Anonymous, New Orleans, US

9. Questioning my rationale. Since I wrote Rationality, people ask if I always act rationally. Counterexamples spring to mind, from biking aggressively to postponing medical tests because I may not like the results.

10. Listening to music at the gym. I had struggled to turn fitness into a routine, but listening to music while working out has made me feel powerful and alive. Metallica is the best, but any 80s or 90s metal does the trick. Victor Gonzalez, product designer, Los Angeles, US

15. Rescuing trapped bees. They get stuck by our kitchen skylight, buzzing in panic. Shooing them with a magazine only makes them panic more. It’s frustrating and a little heartbreaking. But, recently, I discovered that they will nestle long enough on a feather duster for me to take them outside. Tim Dowling, Guardian writer and columnist

16. Taking part in parkrun. I was already running a lot, but parkrun showed me the power of community and being active without competition, as well as how enriching volunteering can be. Matt Ford, IT technician, Örebro, Sweden

25. Realising I must cry, whether faced with joy or sadness. When my granddaughter died in 2021, I felt as if I had to be strong, but my body broke down and I was ill. Eventually, I let myself cry.

26. Using my gua sha before bed. I keep my gua sha – a smooth, flat crystal for massaging my face – on my nightstand so it’s easy to remember to use it.

31. Reading the ingredients on my food. Everything was full of emulsifiers, flavourings, colourings, humectants, stabilisers, preservatives, modified starches and sweeteners.

46. Cutting my hair short. When travelling, I was always jealous of my boyfriend, who could easily wash his hair in a sink. Then I started doing more sport and again I was jealous of the boys with their short hair. Eventually, I got my hair cut and it was one of my wisest decisions. Veronika Shirobokova, English teacher, Russia

47. Borrowing books from the library. I read a lot more now, since it’s less stressful for my eyes than using an e-reader. Reading is like meditation: a great joy that fills me up. I find it very relaxing and interesting; it’s a great way to unwind. Zohara Derry, self-employed, Israel

48. Carving out more hours than I think I need for sleep. After a brief stint wearing a sleep tracker, I realised I wasn’t getting as much shuteye as I thought. Now, if I want to get eight hours of sleep, I give myself nine hours to achieve it. Coco Khan, writer and co-host of Pod Save the UK

49. Thinking about my future self. If I don’t feel like putting away my laundry, for example, I think about my future self an hour from now also not wanting to put away the laundry. Then I put it away immediately, to help make her life easier. It has been surprisingly helpful. Katie, Chicago, US

Chitra Ramaswamy, writer and author of Homelands: The History of a Friendship

53. Regularly swimming laps at my local pool. I go most days and churn out 1,000 to 1600 metres a session. Swimming is the closest thing there is to flying; when I’m in the zone, it provides me with a deep meditative space. Michael Mueller, higher education employee, Pennsylvania, US

55. Taking better care of my skin. An aesthetician helped me plan routine care with specific products.

64. Going for a daily coffee date. My wife and I go to a local cafe every day. It may seem inconsequential, but it brings incalculable amounts of joy on so many levels. It’s the small things, precious and fragile, that can change your life. Christian Cerises, retired chef, California, US

65. Consciously choosing my first and last thoughts each day. We have 60,000 to 80,000 thoughts a day, but 80% of them are repetitive and negative. Every morning, I choose an empowering thought; every night, I choose a grateful thought, which helps shift my mindset. Jay Shetty, life coach

66. Cutting out milk. While staying with friends who didn’t drink milk, I grumblingly used their oat milk for my coffee and discovered I was free of the intestinal cramps that had plagued me. I had no idea you could become lactose intolerant later in life. Ellen Gruber Garvey, English professor, New York, US

69. Buying secondhand clothes.Not because I’m particularly sustainability-minded, but because I’m cheap.

Joel Golby, writer and author of Four Stars

70. Switching to two twin-sized down duvets, rather than sharing a queen-sized sheet and blankets with my husband.

Samuel Browne, operating department practitioner, Sheffield

83. Replacing all my socks with identical black pairs. It’s a tip I found in a book on ADHD and it’s made getting ready in the mornings much easier. It’s definitely helped with my decision fatigue. Anita Bhagwandas, beauty and lifestyle writer

93. Noticing moments of safety. When I’m comfortable, cosy or just entertained, I turn my attention toward that sensation, in the way I would notice a puppy snuggling in my lap.
