生活的唯一方式是接受不可接受的事物。

每一项伟大的工程成就都始于一个清晰的愿景。

企业家精神的核心是创新，而创新的本质是冒险。

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.
