I have often tried to imagine how I might have acted differently. Always I end up in the same place.

Thinking has, many a time, made me sad, darling; but doing never did in all my life... My precept is, "Do something, my sister, do good if you can; but, at any rate, do something".

We are dying from overthinking. We are slowly killing ourselves by thinking about everything. Think. Think. Think. You can never trust the human mind anyway. It's a death trap.

Thinking too much just brings it back to me, me, me—but thanking takes my eyes off myself and my mistakes and puts them on others, on things bigger than myself. I can’t stand here very long without being humbled at how small I am and amazed at how big and beautiful our world is.

Those only are happy (I thought) who have their minds fixed on some object other than their own happiness; on the happiness of others, on the improvement of mankind, even on some art or pursuit, followed not as a means, but as itself an ideal end. Aiming thus at something else, they find happiness by the way. The enjoyments of life (such was now my theory) are sufficient to make it a pleasant thing, when they are taken en passant, without being made a principal object. Once make them so, and they are immediately felt to be insufficient. They will not bear a scrutinizing examination. Ask yourself whether you are happy, and you cease to be so. The only chance is to treat, not happiness, but some end external to it, as the purpose of life. Let your self-consciousness, your scrutiny, your self-interrogation, exhaust themselves on that; and if otherwise fortunately circumstanced you will inhale happiness with the air you breathe, without dwelling on it or thinking about it, without either forestalling it in imagination, or putting it to flight by fatal questioning.

That’s what comes of overthinking things. On a more pragmatic level, we do things simply because we do them. I wrote this book because I couldn’t not write it. To stop myself from creating art would be as absurd as changing my personality and mannerisms entirely to become a wholly different person.
