不管你是年轻还是年老，我还是会做我自己。

Facts are stubborn things; and whatever may be our wishes, our inclinations, or the dictates of our passion, they cannot alter the state of facts and evidence.

You have to be able to adapt to changing market conditions. If you can't adapt, you won't survive.

心理学必须阐明心灵的实际运作。

正派人的话，明明知道了为了我好，内心感激却未必高兴；奸邪人的话，明明知道是在奉承我，但听着十分顺耳，所以未必生气。由此可知听取忠言是多么艰难。

当我接受自己本来的样子时，我就能改变。
