幸福的幸里面是一个“幸”，不是一个“辛”。  或者理解成，Y=Why=为什么，I=我。幸福里面没有为什么，只有我。 

I think goals should never be easy, they should force you to work, even if they are uncomfortable at the time.

For every dollar you spend purchasing something substantial， expect to pay a dollar in repairs， maintenance， or disposal by the end of its life.
