It may happen that your life   43    greatly on your preference of your one choice to the other．
In fact that is what   44   is like；we are often   45   with the two opposite sides of a thing which are both  46    like a newspaper cutting．It often occurs that our attention is   47   to the thing only after we get into another．The former may be more important than the latter and this   48   a divided mind．I still remember a philosopher’s   49 ：“When one door shuts，another opens in life．”So a casual（不经意的）    50   may not be a bad one．
