Do you know what makes you happy? Write a list of all the things that make you happy. How many of them are fun? Most of them? So, if you spend your time doing all these fun things, you’ll be really happy, won’t you?
Well, maybe not. For most people, fun isn’t enough for real happiness. Paul Dolan wrote a book called Happiness by Design. 1. If most of the things on your list are about pleasure, that is what you think makes you happy. But you also need activities with purpose.
2. It’s easy to do well in subjects you like, but subjects you don’t like are less motivating. They’re not fun for you, but you have to study them so you need to find purpose. An “A” in a subject you hate won’t help the world. 3. Each person can study one part until they understand it and then teach it to the rest of the group. The purpose becomes helping the team.
Go back to your list of things that make you happy. 4. Can you add any? Remember, some activities might bring both pleasure and purpose.
Now you need to design a happy life. Paul Dolan believes people should “decide, design, do”. First decide what brings you pleasure and/or purpose -that means your two lists. 5. For example, you might love riding a bike but never have time to do it. So, ride to school or the library or the shops. Some parts of our lives are good or bad luck, but we can still design the rest to make more happiness.
A.But can you be part of a study team with friends?
B.How many of them are activities that bring purpose?
C.There are different ways we can find pleasure in things.
D.He thinks happiness comes from both pleasure and purpose.
E.If you’re a student, your “job” is studying and passing exams.
F.If you think something makes you happy, then it makes you happy.
G.Then, don’t just think about these activities, fill your life with them.

Do teenagers know how to sleep? If you’re the parent of teens, you might be laughing to yourself. That’s all they know how to do. In truth, teens might not know enough about how to sleep, when to sleep and why.1. .
Just as we focus on our diets and exercise for health, we need to consider sleep necessary to our mental, physical and psychological health. “Good” sleep is sleep that is long enough to allow your brain to remove the side effects of daytime brain activity. Consistent bed times and wakeup times are the key to keeping our sleep cycles.2..
Teens are social creatures, and the most attractive social “gathering” place these days is on their digital devices.3.. Ideally, we should avoid blue light for at least half an hour before bed. But social media and homework that requires screen time mean too many kids are powering up their devices when their bodies should be powering down for the night.
4.. Equally contributing to sleep issues are eating too late, taking naps, and failing to get enough exercise. In other words, these people never learned how to sleep.
Over time, poor sleep leads to a decline in mood.5.. Significantly, when I speak to my adult patients who are struggling with sleep issues, nearly all of them say their sleep problems started in high school.
Therefore, I recommend sleep education. Otherwise, we won’t necessarily solve the health, safety and economic issues of sleepy teens.
A. When they are disturbed, our sleep is affected
B. Going to bed too late is only one part of sleep problems
C. Being exposed to blue light from our screens delays sleep
D. Current school schedules allow for about seven hours of sleep a night
E. It also contributes to a lot of medical issues, from being fat to heart disease
F. Later school start time really contributes to more sleep and improved health
G. As far as I’m concerned, one important element is missing: sleep education
