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. You will feel very good.

Exercise regularly and eat well. Don’t rush through your meals. Eat less junk food or fast food. Eat healthy food instead. Fruits and vegetables are necessary.
Get to know pleasant people. Some people are optimistic, while others are not. Choose optimistic people as your friends and spend more time with them and you’ll be as happy as them. You’ll see everything with the optimism.
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﹡.
