Life comes in a bag. This bag includes happiness and sadness, failure and success, hope and despair. Experiences in life teach us new lessons and make us a better person. With each passing day we learn to deal with various (各种不同的) situations.
Love
Love plays a main role in our life. Love makes you feel wanted. In the early stage of our life, our parents are the ones who show us with love and care. They teach us about what is right and wrong, good and bad. But we don't always care about it. It is only after having kids that a person understands others' feelings.
Happiness and sadness
Happiness can bring people a peaceful mind. No mind is happy without peace. Sadness is the cause of death of a loved one or the failure.
Success and failure
Failure is the path to success. It helps us to touch the sky, teaches us to survive and shows a specific way. Success brings in money, pride and self-respect.
Hope and despair
Hope is what keeps life going. Parents always hope their children will do well. Hope makes us dream. Hope builds in patience.
