Every week, sometimes every day, someone writes to me asking for advice about the career they should take. I can’t, unfortunately, respond to them all, so I thought I should try to formulate some general guidelines, which I hope people will be able to adapt to their own circumstances. This advice applies only to those who have a genuine choice of careers, which means, regrettably, that it does not apply to the majority of the world’s workforce. But if the people writing to me did not have choice, they wouldn’t be asking.
We’ve known for a while that excessive screen time is not good for your sleep schedule, but the latest findings are overwhelmingly gloomy – and extend well beyond insomnia.
An eye doctor says he’s recently seen a few 35-year-old patients whose lenses, which are typically clear all the way up until around age 40, are so cloudy they resemble 75-year-olds’. A sleep doctor says kids as young as toddlers are suffering from chronic insomnia, which in turn affects their behavior and performance at school and daycare. A scientist finds that women who work night shifts are twice as likely to develop breast cancer than those who sleep at night.
What do all these anecdotes have in common? Nighttime exposure to the blue light emanating from our screens.
You’ve probably heard the hype these past few years: being in the presence of light at night disrupts the body’s natural circadian rhythms by suppressing the production of melatonin, a sleep hormone. But melatonin does far more than help us get sleepy – it’s also an antioxidant that appears to play a pivotal role in slowing the progression of cancer and other diseases.
“I’ve been spending a lot of the past 20 years worrying about it,” said Dr. Richard Hansler, who clocked in 42 years at GE Lighting developing “all kinds of bright, beautiful lights” before his move to John Carroll University in Ohio, where he studied the effects of light at night on our health. It was the mid 1990s, and at that point, he said, his concern wasn’t widely shared.

While on holiday in Florence last week, I saw this beautiful painting in the Uffuzi Gallery. Painted in the fifteenth century, it’s an allegory of success. Riding on the head of a dolphin, holding a sail, hoping to catch the fickle winds of fortune, I think it’s about as apt an allegory for the vagaries of success as any I can imagine.

ONE of the biggest complaints in modern society is being overscheduled, overcommitted and overextended. Ask people at a social gathering how they are and the stock answer is “super busy,” “crazy busy” or “insanely busy.” Nobody is just “fine” anymore.
When people aren’t super busy at work, they are crazy busy exercising, entertaining or taking their kids to Chinese lessons. Or maybe they are insanely busy playing fantasy football, tracing their genealogy or churning their own butter.
And if there is ever a still moment for reflective thought — say, while waiting in line at the grocery store or sitting in traffic — out comes the mobile device. So it’s worth noting a study published last month in the journal Science, which shows how far people will go to avoid introspection.
