For great and low there's but one test: 'Tis that each man do his best.

There is a force that somehow pushes us to choose the more difficult path whereby we can transcend the mire and muck into which we are so often born. Despite all that resists the process, we do become better human beings.

Patience and perseverance have a magical effect before which difficulties disappear and obstacles vanish.

Half-finished work generally proves to be labor lost.

Perseverance is more prevailing than violence; and many things which cannot be overcome when they are together, yield themselves up when taken little by little.

Against all odds and despite all the obstacles, we are going to make it.

Give us grace and strength to forbear and to persevere. Give us courage and gaiety and the quiet mind, spare to us our friends, soften to us our enemies.

Good business leaders create a vision, articulate the vision, passionately own the vision, and relentlessly drive it to completion.

And, more importantly, reach for the stars. And realize that it is never too late—not now, not ever—for you to pursue you passion, your pursuit of perfection. And most importantly, your perseverance for making it happen.

If we all can persevere, if we can in every land and office look beyond our own shores and ambitions, then surely the age will dawn in which the strong are just and the weak secure and the peace preserved.

It isn’t enough to talk about peace. One must believe in it. And it isn’t enough to believe in it. One must work at it.

One worthwhile task carried to a successful conclusion is worth half-a-hundred half-finished tasks.

No one who does good work will ever come to a bad end, either here or in the world to come.

When you see that in order to produce, you need to obtain permission from men who produce nothing - When you see that money is flowing to those who deal, not in goods, butt in favors - When you see that men get richer by graft and by pull than by work, and your laws don’t protect you against them, but protect them against you - When you see corruption being rewarded and honesty becoming a self-sacrifice - You may know that your society is doomed.

Do not think that what is hard for you to master is humanly impossible; but if a thing is humanly possible, consider it to be within your reach.

It’s not when you realize that nothing can help you—religion, pride, anything—it’s when you realize that you don’t need any aid.

Be true to your work, your word, and your friend.

One who is serious all day will never have a good time, while one who is frivolous all day will never establish a household.
