things in the world are changing. people are changing and every creature is changing. changing is a neutral word. we can’t judge it is good or bad in general, because every coin has two sides. but sometimes we need to change, because it is good for us. sometimes we will meet some difficult or uncomfortable situation. when we are not able to change it, we need to change ourselves. if both of us refuse to budge, the problem would not be solved. sometimes we need to change our life attitude; sometimes we need to change our views of seeing things; sometimes we need to tolerant; sometimes we need to be strong. changing ourselves according to the specific situation is good for us.
