Paul Dirac was one of the greatest physicists of the 20th century. He was a pioneer in quantum(量子) theory, which shaped our modern world. Dirac was also a genius when it came to analytical thinking. But when his colleagues asked him for advice, his secret to success had nothing to do with the traditional scientific method. “Be guided,” Dirac told them, “by your emotions.”

Dirac’s advice, like his physics, ran against the common assumption of psychology in his day: that logical thought primarily drives our behaviors, and that when emotions play a role, they are likely to keep us off our best judgment.

Today, researchers have gained a deeper understanding of emotions and how they can positively influence logical choices. In a study led by Professor Mark Fenton, his team conducted interviews with 118 professional traders at four investment banks. They found that even among the most experienced traders, the lower-performing ones seemed less likely to effectively engage with the emotions guiding their choices—whether to buy or sell a set of securities, for example, with millions of dollars at risk. The most successful traders, however, were particularly likely to acknowledge their emotions and followed their direct feelings about stock options(股票期权) when they had limited information to draw on. They also understood that when emotions become too intense, toning them down can be necessary. The issue for the successful traders was not how to avoid emotions but how to control them.

Welcoming emotions into the decision-making process can help us be more clear-eyed about where our choices come from. Dirac knew that emotions helped him look beyond the beliefs of his contemporaries. Again and again, his controversial ideas proved correct. Dirac passed away in 1984, a couple of decades before the revolution in emotion theory began, but he’d been happy to see that he’d been right again.

Have you ever felt nervous or afraid to take time off from work to look after your mental health?

Marisa Kabas, a writer and political strategist, recently posed a similar question on Twitter (推特网), inspired by Simone Biles, who stopped taking part in Olympic events this week to protect her mental health.

“It was so shocking to so many people,” Ms. Kabas said on Wednesday in an interview. “Because the whole mentality (心态， 思维方式) is to be strong, and push through the pain.”

If you’re unlikely to use sick days for mental health reasons or are scared of being punished for doing so, I experts say it’s time to start thinking about how to protect your mental well-being. You should take a “sad day”.

There’s no official definition for a “sad day,” also known as a mental health day. Typically, it is paid time off drawn from sick days(or personal days) to help employees who aren’t feeling like their usual selves, offering an opportunity to refresh their minds, do something meaningful; or simply take a break from daily stressors. The “sad day” is only a temporary (暂时的) fix, and not meant to address deeper problems, but sometimes a little time away can make a big difference.

In most situations, just say that you need to take a sick day, and leave it at that, the experts advised. “I think the safe advice is not to be honest and frank,” said Andrew Kuller, a clinical psychologist. Not everybody values mental health, he added, and “unless you’re close with your boss, it is a risk. But say you work at the type of organization where you can tell the truth without fear of being punished. In that case, you still don’t need to reveal why you want to take a sick day.”

Whatever you do, don t spend the mental health day feeling guilty. So instead of thinking, “I should be at work right now, try to reframe your thinking in a more positive way. For example, try saying: “It would be great; if I could be at work right now. But today is a day that I need to take care of myself, so that’s what I’m going to do.”

If you are hungry, what will you do? Grab a piece of your favorite meal and stay quiet after that? Just like stomach, even your mind will be hungry. But it never lets you know, because you keep it busy thinking about your dream lover, favorite star and many such absurd things. So it silently begins to hide your needs and never lets itself grow. When mind loses its freedom to grow, creativity gets its full stop. This might be the reason why we all sometimes think “What happens next？”， “Why can't I think？”， “Why am I always given the difficult problems？” Well, this is the after­effect of using our brain for thinking of not­so­worthy things.

Hunger of the mind can be actually satisfied through extensive reading. But why is it reading but not watching TV? Because reading has been the most educational tool used by us right from the childhood. Just like that to develop other aspects of our life, we have to turn to reading for help. You have a number of books in the world which will answer all your “how­to” questions. Once you read a book, you just don't run your eyes through the lines, but your mind decodes (译解) it and explains it to you. The interesting part of the book is stored in your mind as a seed. Now this seed is unknowingly used by you in your future to develop new ideas. The same seed, if used many times, can help you link and relate a lot of things, which you would never think of in your wildest dreams！This is nothing but creativity. The more books you read, the wider your mind will become. Also this improves your oratorical (speech­making) skills to a large extent and also makes a significant contribution to your vocabulary. When you start speaking English or any other language fluently with your friends or other people, you never seem to run out of the right words at the right time.

Actually, I had a problem in speaking English fluently，but as I read, I could improve significantly. So guys, do join me and give food for your thoughts by reading, reading and more reading. Now what are you waiting for? Go, grab a book and let me know!
