"Memory can make a thing seem to have been much more than it was."

我一直认为，机器的真正考验在于它在普通劳动者手中的实际效用。

个人的不是私人的；它是政治的。

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.
