There are times that the surrounding world which we thought very familiar to us might not have been understood by us comprehensively.Sometimes,only when we change the perspective through that we observe the questions,when we emancipate our minds from fetters of previous eyeshot and adjust ourselves to new eyeshot and new thinking,we are likely to see the light and find out the brand new feeling and interest.The life I comprehend is actually this kind of endless exploration;we strive always till the final destination comes.
