Sustainability isn't a choice—it's our responsibility to future generations.
"To understand a person, you must first understand their silences."
If you're not stubborn, you'll give up on experiments too soon. And if you're not flexible, you'll pound your head against the wall and you won't see a different solution to a problem you're trying to solve.
几个世纪以来纸张一直是人类知识的载体,我们的责任是确保它再延续几个世纪。#
