你能做的最好的投资就是投资自己。
The best investment you can make is in yourself.
You do not need to leave your room. Remain sitting at your table and listen. Do not even listen, simply wait. Do not even wait, be quite still and solitary. The world will freely offer itself to you to be unmasked, it has no choice, it will roll in ecstasy at your feet.
I don't compete with anyone but myself. My goal is to be better than I was yesterday.
译文：陛下你实在应该广泛地听取别人的意见，来发扬光大先帝遗留的美德，振奋有远大志向的人的志气，不应过分看轻自己，援引不恰当的譬喻，以至于堵塞忠言进谏的道路。
自由不是做我们想做的事情的权力，而是做我们应该做的事情的权利。
金钱可以为你买到爱。
Your most unhappy customers are your greatest source of learning.
