Maybe it is true that we do not know what we have got until we lose it, but it is also true that we do not know what we have been missing until it arrives. It takes an hour to like someone, and a day to love someone, but it takes a lifetime to forget someone. Giving someone all your love is never an assurance that they will love you back. Do not expect love in return; but if it does not, be content it has grown in yours. Do not rely on one's appearance; it can trick you. Do not rely on wealth; even that fades away. Rely on someone who makes you smile, because it takes only a smile to make a dark day seem bright. There are moments in life when you miss someone so much that you just want to pick them from your dreams and hug them. Dream what you want to dream, go where you want to go; be what you want to be, because you have only one life and one chance to do all the things you want to do. The brightest future will always be based on a forgotten past. You cannot go on well in life until you let your past failures and heartaches go off. May you have enough happiness to make you sweet, enough trials to make you strong, enough sorrow to keep you human, enough hope to make you happy. The happiest of people do not necessarily have the best of everything; they just make the most of everything that comes along their way. Happiness waits for those who cry, those appreciate the importance of people who have touched their lives. Always put yourself in others' shoes. If you feel that it hurts you, it probably hurts the other person, too. When you were born , you were crying and everyone around you was smiling . Live your life so that when you die , you are the one who is smiling and everyone around you is crying . In this passage, the writer wants to tell us_. A) what to do in our life B) where to go with other persons C) how to treat our life D) how to get on well with other persons
