Niels Bohr on luck

Prediction is very difficult, especially about the future.

Anyone who says that they can contemplate quantum mechanics without becoming dizzy has not understood the concept in the least.

Never express yourself more clearly than you are able to think.

Chance favors the prepared mind.

Louis Pasteur1822–1895

I am a strong believer in luck and I find the harder I work the more I have of it.

I think luck is the sense to recognize an opportunity and the ability to take advantage of it… The man who can smile at his breaks and grab his chances gets on.

Samuel Goldwyn1882–1974
