Learn to relax. Overwork is the main reason why so many students feel tired and stressed. Cut down some of the jobs you need to do each day so that you can only focus on the most important things. Leave time for activities that are relaxing and fun. This might mean reading a good book, listening to the music, going for a walk or taking a relaxing bath.
Get a good night’s sleep. Getting enough sleep will help you keep your body and mind in the best form. If you stay up late and need to get up early for school the next day, you may not be able to concentrate on the things you need to do.
Exercise regularly and eat well. Don’t rush through your meals. Eat less junk food or fast food. Eat healthy food instead.
Get to know pleasant people. Some people are optimistic, while others not. Choose optimistic people as your friends and spend more time with them and you’ll be as happy as them.
Learn to be calm when you face any problem. Find out the best option from those that are in your mind. Knowing that you are able to solve problems is a good way to build up your self-confidence.
Have a happy attitude. Your attitude decides the way you see things. Is your cup half full or half empty? Learn to think more positively(积极地) about the difficulties you face.
