夫國(guó)者人之積也,人者心之器也,而國(guó)事者一人群心理之現(xiàn)象也。是故政治之隆污,系乎人心之振靡。吾心信其可行,則移山填海之難,終有成功之日;吾心信其不可行,則反掌折枝之易,亦無(wú)收效之期也。心之為用大矣哉!夫心也者,萬(wàn)事之本源也。
——《建國(guó)方略·孫文學(xué)說(shuō)》(1917—1919年)
Ignoring isn’t the same as ignorance, you have to work at it.
If you’re not willing to work hard, don’t expect success.
The study of psychology is the study of adaptive success.
A scientist’s greatest tool is not just their intellect but their imagination.
