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.

Technology should serve humanity, not the other way around.

True courage is not the absence of fear, but moving forward in the face of fear.

Truth is, everybody is going to hurt you; you just gotta find the ones worth suffering for.

The strength of a leader lies in their ability to adapt and inspire others to embrace change.
