心灵不是世界的一面镜子，而是应对世界的工具。

Keep all your things visible in a hotel room， not in drawers， and all gathered into one spot. That way you’ll never leave anything behind. If you need to have something like a charger off to the side， place a couple of other large items next to it， because you are less likely to leave 3 items behind than just one.

真正的科学首先教会人怀疑与承认无知。

In every word, there is a world waiting to be discovered.
