There are so many annoyances in our life , which can be concluded four parts : Can't let it go ; can't figure it out ; can't see it through ; can't forget it . The reason why we are so tired in our heart is that we often hesitate between abandon and persistence . We are no sure whether to do or not . The reason why we feel puzzled is that we would like to see things nagtively . Can't extricate ourselves from it . The reason why we are unhappy is that we have so much appetite , in stead of what we have too little . And the reason why we would feel agony is that we have a good memory , remembering something good and bad .

Get rid of these four parts , and your life will be so wonderful .
