The earth gives us its treasures, but it's our duty to give back more than we take.
释义:不需要让自己过于饱食,把每时每刻都用来做有益的事情,不放弃任何一寸时间,这样才能够充分利用时间,有所成就。
Words are wise men's counters, they do but reckon by them; but they are the money of fools.
Why worry? If you’ve done the very best you can, worry won’t make it any better.
