    Most of us lead a busy life.____We think, “If I reached my goal, then I would be happy”, or “If I could get a better job, then I would enjoy life.” But why not enjoy life right now?

    Firstly, take time to notice and appreciate the beauty in your own surroundings.____ “There is a great big world of wonder and beauty around us!” And as Brodersen explains, “Look for the beauty of the sunrise and of a friend's smile that brightens your day. Open your eyes to see the beauty you might not normally see. Doing so helps to cheer you up.”

    Secondly, taking time to experience some simple pleasures also can bring joy to your heart and ease your stress. Take me for example.____One universal simple pleasure is finding things that make you laugh. Make time to laugh every day.

    Thirdly, don't take your family and friends for granted. Rich, rewarding relationships add greatly to the enjoyment of life. When you think of someone, why not call, e-mail or write them?____As Wayne Lawton explains, “Invest time in relationships. Remove the attitude, what's in it for me? Happiness is found in putting other's interests, desires and concerns ahead of our own whenever possible. Selfishness is a dead-end street.”____

A. Be aware of beauty in nature.

B. So please treasure relationship.

C. You don't need to travel far to find beauty.

D. Driven by the “urgent”, we forget to enjoy life.

E. In my spare time, I enjoy collecting stamps and reading novels.

F. A short e-mail or phone call can make a world of difference to someone.

G. I delight in simple things like my favorite tea drink, a bubble bath or family photos.
