"The world is changed by your example, not your opinion."
~ Paulo Coelho
You can quietly lead by example or you can push others away by being so opinionated that you alienate yourself from the world. Those who choose the latter will often find themselves on a very high pedestal so far up that they can not see the people that they are trying to change.
The pattern of a river will change over time. The water will erode the rocks and it will start to look different or a new path will be created. The river does not plot to change the earth, it just does what it is suppose to do, flow.
If we live out our lives with intent, love and compassion it will make more of an impact than that person yelling from their pedestal way up high.
