智力不仅仅是推理的能力；它还包括在记忆中寻找相关材料并在需要时调动注意力的能力。

The human heart is the most deceitful of all things, and desperately wicked. Who really knows how bad it is?

译文：不怕自身会产生恶念，只怕发觉自身的恶念太迟。

Money is overrated. Truly new things rarely need an abundance of money. If that was so， billionaires would have a monopoly on inventing new things， and they don’t. Instead almost all breakthroughs are made by those who lack money， because they are forced to rely on their passion， persistence and ingenuity to figure out new ways. Being poor is an advantage in innovation.

Be a good ancestor. Do something a future generation will thank you for. A simple thing is to plant a tree.
