...successful research doesn't depend on mathematical skill, or even the deep understanding of theory. It depends to a large degree on choosing an important problem and finding a way to solve it, even if imperfectly at first. Very often ambition and entrepreneurial drive, in combination, beat brilliance.

The only way to have real success in science, the field I'm familiar with, is to describe the evidence very carefully without regard to the way you feel it should be. If you have a theory, you must try to explain what's good and what's bad about it equally. In science, you learn a kind of standard integrity and honesty.

Optimism is the one quality more associated with success and happiness than
any other.

Optimism is the faith that leads to achievement; nothing can be done without hope.

Optimism is the faith that leads to achievement.

Before we go further we should define what optimism is. Real optimists don’t believe that everything will be great. That’s complacency. Optimism is a belief that the odds of a good outcome are in your favor over time, even when there will be setbacks along the way.

The scientist has a lot of experience with ignorance and doubt and uncertainty, and this experience is of very great importance, I think. When a scientist doesn’t know the answer to a problem, he is ignorant. When he has a hunch as to what the result is, he is uncertain. And when he is pretty damn sure of what the result is going to be, he is still in some doubt. We have found it of paramount importance that in order to progress, we must recognize our ignorance and leave room for doubt. Scientific knowledge is a body of statements of varying degrees of certainty — some most unsure, some nearly sure, but none absolutely certain. Now, we scientists are used to this, and we take it for granted that it is perfectly consistent to be unsure, that it is possible to live and not know. But I don’t know whether everyone realizes this is true. Our freedom to doubt was born out of a struggle against authority in the early days of science. It was a very deep and strong struggle: permit us to question — to doubt — to not be sure. I think that it is important that we do not forget this struggle and thus perhaps lose what we have gained.

We continually remember before our God and Father your work produced by faith, your labor prompted by love, and your endurance inspired by hope in our LORD Jesus Christ. 1 THESSALONIANS 1:3 OCTOBER 9 To be a true optimist, you have to be rugged and tough in mind. An optimist is a person who believes in a good outcome even when he can’t yet see it. He is a person who believes in a greater day when there is yet no evidence of it. He is one who believes in his own future when he can’t see much possibility in it. A lot of people live under a cloud. But up above the clouds, the sun is always shining. Down here, on the surface of the earth, groping around in the shadows under a low ceiling, a person may not feel optimistic. But you ought to begin to practice optimism. Send up into the mass of dark clouds bright, powerful optimistic thoughts, a bright optimistic faith. By so doing, you can actually dissipate the clouds and have an entirely different life. Constantly send up into the overcast sky that is blanketing your mind bright thoughts of faith, love, hope, thoughts of God, thoughts about the greatness of life.

Optimism is a strategy for making a better future. Because unless you believe that the future can be better, you are unlikely to step up and take responsibility for making it so.

Our theory had been that optimism matters because it produces persistence.

Optimism is a strategy for making a better future. Because unless you believe that the future can be better, it’s unlikely you will step up and take responsibility for making it so. If you assume that there’s no hope, you guarantee that there will be no hope. If you assume that there is an instinct for freedom, there are opportunities to change things, there’s a chance you may contribute to making a better world. The choice is yours.

I am an optimist. Anyone interested in the future has to be otherwise he would simply shoot himself.

Optimism is the most important human trait, because it allows us to evolve our ideas, to improve our situation, and to hope for a better tomorrow.

I like the scientific spirit — the holding off, the being sure but not too sure, the willingness to surrender ideas when the evidence is against them: this is ultimately fine — it always keeps the way beyond open — always gives life, thought, affection, the whole man, a chance to try over again after a mistake — after a wrong guess.
