Let us think only of the good days that are to come.
To the question whether I am a pessimist or an optimist, I answer that my knowledge is pessimistic, but my willing and hoping are optimistic.
— Albert Schweitzer
Philosophy
[Americans have] a continuing normative commitment to the ideals of individual freedom and mobility, values that extend far beyond the issue of race in the American mind. The depth of this commitment may be summarily dismissed as the unfounded optimism of the average American—I may not be Donald Trump now, but just you wait; if I don't make it, my children will.
"I'd rather be optimistic and wrong; than pessimistic and right."
Every one of the great revolutionists, from Isaiah to Shelley, have been optimists. They have been indignant, not about the badness of existence, but about the slowness of men in realizing its goodness.
— G. K. Chesterton
Optimism
A time when all such good things will be for all men may be coming more nearly than we think. Each one who believes that brings the good time nearer; each heart that fails delays it.
— H. G. Wells

[...] although the world is full of suffering, it is full also of the overcoming of it. My optimism, then, does not rest on the absence of evil, but on a glad belief in the preponderance of good and a willing effort always to coöperate with the good, that it may prevail. I try to increase the power God has given me to see the best in everything and every one, and make that Best a part of my life.
I, too, can work, and because I love to labor with my head and my hands, I am an optimist in spite of all. I used to think I should be thwarted in my desire to do something useful. But I have found out that though the ways in which I can make myself useful are few, yet the work open to me is endless.
Optimism, then, is a fact within my own heart. But as I look out upon life, my heart meets no contradiction. The outward world justifies my inward universe of good.
