It is not a very fragrant world, but it is the world you live in.

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.

The future belongs to those who prepare today.

When I look at the world I'm pessimistic, but when I look at people I am optimistic.
