This is a Famous article written by the American writer Helen Keller, who was both deaf and blind.
In this passage Helen mainly warned us to be aware of our listless attitude towards life. And asking us to care the things we always thought to be ordinary. Finally, her advise of "it would be an excellent rule to live each day as if we should die tomorrow" Gives me the deepest impression.
Maybe our able men can never feel the bitterness of a disabled person, thus neglect the blessings of seeing and hearing, and It's quite a pity that seeings see little.
I don't quite understand, however, if it is always a golden rule to regard each day as the last one, and this doubt reminds me of a kind of students. Every day they hurried to classroom in the morning, and rushed to the dining hall at noon. They walk faster than others to save time to study, seeing nobody on the road. They seldom speak to others and are regarded as eccentric people. it is true that they are time saving ones, and maybe regard everyday as the last day in life, but I can never accept this kind of life style.
I always take them as negative examples in my mind, I can hardly guess what on earth they are liveing for. Perhaps they live for study. Study is not everything, but the only thing. And I feel sorry for them.
I never deem study an unimportant thing, but it is far from the only thing. We stil have a lot more to cherish.
First of all, We should have love in our life.we always get love from our family, friends, and even some strangers who offer help to us, and equally importantly we should show our love to life, to the ones who love us, to strangers or animals and even to objects. What's more, we should appreciate everything that life has offer to us, even those sufferings. Sometimes we can get a lot more in sufferings than in joys. I am strongly convinced that there are no trivial things in life and no useless man. Every creature has its own meaning to exist in this lovely world.
In order to appreciate life we should notice every detail in life, including trifles like weather and food to bigger ones such as country and politics. Make the full use our God given faculties is the mainly task I think everyone of us should learn, and you can naturally acquire this ability if you try to keep your eyes open to all the aspects life.

The Wind in the Willows is a classic of children's literature by Kenneth Grahame, first published in 1908. Alternately slow moving and fast paced, it focuses on four anthropomorphised animal characters in a pastoral version of England. The novel is notable for its mixture of mysticism, adventure, morality, and camaraderie.
The Wind in the Willows was saved from obscurity by the then-famous playwright, A. A. Milne, who loved it and adapted a part of it for stage as Toad of Toad Hall. The book made Grahame's fortune, enabling him to retire from his bank job, which he hated, though it was respectable and well-paid. He moved to the country, where he spent his time by the River Thames doing much as the animal characters in his book do; namely, as one of the most famous phrases from the book says, "simply messing about in boats".
