我们生活在一个边际效用递减的时代。每一件有需求的事情，看起来都已经有了又不是不能用的解决方案。
对于已经习惯了某件事物的人，你很难去向他介绍任何你觉得更好的解决方案。你只能去做一些非常不同的，这样别人或许才会有那么一点点来了解的欲望。
We live in an era of diminishing marginal utility. For every thing that is in demand, it seems that there is already a solution that is not unavailable.
For someone who is used to something, it's hard to introduce them to any solution that you think is better. You can only do something very different, so that others may have a little desire to understand.
