You can finish the longest road step by step. But you may be unable to finish the shortest road if you have no action of striding.再长的路，一步步也能走完；再短的路，不迈开双脚也无法到达。

:Life will get better when it goes bad to a certain extent.Because it can't get worse than this.We should fill our heart with sunshine.生活坏到一定程度就会好起来，因为它无法更坏。所以我们心中应该总是充满阳光。
