Sustainability must be profitable, or it won't be sustainable.

Your self-worth is determined by you. You don't have to depend on someone telling you who you are.
出自先秦《荀子·修身》。利益少,但是道义多,这样的事要做。在利与义之间要舍利而取义,强调的是一种修身原则。
Knowledge is the highest wealth of humanity, and sharing knowledge is the greatest generosity.
