Life is not easy for any of us. But what of that? We must have perseverance and above all confidence in ourselves. We must believe that we are gifted for something, and that this thing, at whatever cost, must be attained.

Humanity needs practical men, who get the most out of their work, and, without forgetting the general good, safeguard their own interests. But humanity also needs dreamers, for whom the disinterested development of an enterprise is so captivating that it becomes impossible for them to devote their care to their own material profit.

In science we must be interested in things, not in persons.

My husband and I were so closely united by our affection and our common work that we passed nearly all of our time together.

All my life through, the new sights of Nature made me rejoice like a child.

I have the best husband one could dream of; I could never have imagined finding one like him. He is a true gift of heaven, and the more we live together the more we love each other.

Just remember you will find that one special love that you know is right but for some reason just doesn't last
