We must balance short-term demands with long-term sustainability.

希望是长着羽毛的东西，栖息在灵魂里。

I don't believe in pessimism. If something doesn't come up the way you want, forge ahead. If you think it's going to rain, it will.

Be fearless in the pursuit of what sets your soul on fire.

All my life through, the new sights of Nature made me rejoice like a child.
