My key message to her, as a nine-year-old, recently has been, “You don’t need to be friends with everyone, but you’re forced to respect everyone. And everyone doesn’t need to be friends with you, but everyone is forced to respect you.”

So I urge my sisters, and my brothers, not to be afraid. Be not afraid to denounce injustice, though you may be outnumbered. Be not afraid to seek peace, even if your voice may be small. Be not afraid to demand peace.

I just say, “Follow your instincts.” Don’t feel you have to follow the paths of others, because you may not be temperamentally fitted for it. And so you’ll just harm yourself and your cause and others. But just follow your instinct, and don’t ever pretend to be what you’re not.

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.

[My father] used to say all the time, “You’re in a struggle, but if you get in a fight and lose your temper, you’ll lose the fight. So don’t get mad, get smart.”

Her lesson all the time was “To them to whom much has been given, of them will much be required.”
