Sustainability is no longer an option; it's a necessity for survival in today's world.

To convince someone of the truth, it is not enough to state it, but rather it must be found.

The key to success is to keep growing in all areas of life - mental, emotional, spiritual, as well as physical.

不和屯积钱财的人争较财富多少；不和热心仕途的人争较地位高下；不和骄傲自夸的人争较名声大小；不和年轻力壮的人争较仪容风度，不和逞强好胜的人争较胜负高低。

The only person you should try to be better than is the person you were yesterday.
