5.成功的人生如同登高，一步一步地拾级而上，这中间会有一个个关键的转折点。每当我们走了一段路碰壁了，这一个个转折点又把我们带上了一段段崭新的道路。有时候，转折点就存在于不经意的瞬间，而更多的时候，需要我们付出巨大的努力，人生轨迹才会出现转折。

Success in life is like climbing a height: It has to be done step by step. In the course of this there are certain crucial turning points. Every time we encounter a wall while walking along a stretch of road, we turn into a brand?new stretch of road. Sometimes, a turning point can appear out of nowhere, but most of the time in our lives turning points are only reached as the result of a great deal of hard work.
