My life is so monotonous and, in fact, so uninteresting. Nevertheless I have no feeling of uniformity. And I regret only one thing, which is that the days are so short and they pass so quickly. One never notices what has been done. One can only see what remains to be done. And if one didn’t like the work it would be very discouraging. It seems 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. Perhaps everything will turn out very well, at the moment when we least expect it.
— Madame Curie
