Researchers have found that there are some basic things that you can do to become happier.

◆Self

Yourself includes your education, your health, and your sense of purpose. It is important to take care of yourself and to connect the people around you. First, find a hobby. This gives you a chance to meet people with similar interests. You can also volunteer. Volunteering takes the focus off your own problems and makes you feel grateful for what you have.

◆Home

Create a quieter, dark area where you can sit and relax. Paint your living room yellow – it can increase energy and improve mood (情绪). It also helps to own a pet. Pets can make their owners feel calm, and provide love and friendship.

◆Financial (财务的) life

According to Ed Diener, the key to greater well-being is to have money, but not to want it too much. Try to spend money on things that give you long-lasting pleasure. Buy things that will enrich your life, such as music lessons and dinners with friends and family.

◆Social life

Have friends that encourage you to eat right, to be active, to laugh, and to do your best. Meet with your friends regularly and share with them when you have more of something than you need. Support each other in difficult times.

◆Workplace

Your office should be a place that you like. Find a job with people that you enjoy being around. That includes your boss. And do something that you feel strongly about. That is more important than money.

◆Community

If possible, live near people who have about the same amount of money as you. This makes you less aware (意识到的) of what you don’t have. Live in a neighborhood where you feel safe and where you can walk a lot. Walking makes you healthier, and healthier people are happier people.
