What counsel would you give your twenty-year-old self — and what should they ignore?

I go back to this idea that I only discovered when I was older. I wish I had known it when I was younger, because I think I missed a lot of observations in life. That is to develop your own philosophy. I always thought philosophy was one of the most useless subjects in the world.

My advice to everyone is: “Become a journalist.” ... if you have a chance to be a newspaper reporter for three or four years — before you do whatever you want to do — do it, because you will know so much.

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.

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.

Marry somebody you love and who thinks you being a writer’s a good idea.

Write slowly and by hand only about subjects that interest you. […] Develop craftsmanship through years of wide reading.

Build a good name. Keep your name clean. Don’t make compromises. Don’t worry about making a bunch of money or being successful. Be concerned about doing good work and protect your work. […] Protect your work and if you build a good name, eventually that name will be its own currency.

All over the world, girls are raised to be make themselves likeable, to twist themselves into shapes that suit other people. Please do not twist yourself into shapes to please. Don’t do it. If someone likes that version of you, that version of you that is false and holds back, then they actually just like that twisted shape, and not you.

No. Go for it, as I did it. Go for all the mistakes. I made so many mistakes in doing my films. They all have a stutter or a limp or they are squint-eyed. Hardly anyone notices it, but I notice. Make your mistakes. Get arrested if you trespass. Yes. Do it. There’s nothing wrong with spending a night or two in jail. I’ve done that. Don’t be afraid of the grizzly bear behind you. Travel on foot. Read books.

Spend your time on something meaningful. Not on parties, and not on taking it easy. That’s not good enough. […] When you’re young, you think: Let’s party, do drugs, drink, waste it all, right? But as you get older, you look at what you’ve accomplished. And when you get old, you’ve run out of time. You have to ask yourself: Why am I here? Can I contribute anything to humanity, to society, my work?
