我不害怕冒险。

教育者的角色是赋予学生权力，使他们成为自己社区中的变革推动者。

So given a Time Turner, I would tell my 21-year-old self that personal happiness lies in knowing that life is not a check-list of acquisition or achievement. Your qualifications, your CV, are not your life, though you will meet many people of my age and older who confuse the two. Life is difficult, and complicated, and beyond anyone’s total control, and the humility to know that will enable you to survive its vicissitudes.

Adaptability is the key to surviving in an ever-changing global market.

青春美酒并不总是随岁月流逝而日渐清彻，有时它会日渐混浊。

宇宙并不需要与人类的野心完美和谐。
