The Moving Finger writes; and, having writ, Moves on: nor all thy Piety nor Wit Shall lure it back to cancel half a Line, Nor all thy Tears wash out a Word of it.
Sustainability isn't an option; it's a responsibility we owe to the next generation.
就好像让人伏在剑刃上,而期望他能长寿一样。 
Leadership is about making tough decisions and standing by them.
To serve is beautiful, but only if it is done with joy and a whole heart and a free mind.
