Failure is delay but not defeat. It is a temporary detour, not a dead-end street.

When you’re committed to something, you accept no excuses; only results.

There is no failure except in no longer trying.

Now what should happen when you make a mistake is this: You take your knocks, you learn your lessons and then you move on. That’s the healthiest way to deal with a problem.

To establish true self-esteem, we must concentrate on our successes and forget about the failures and the negatives in our lives.

Far better it is to dare might things, to win glorious triumphs, even though checkered by failure, than to take rank with those poor spirits who neither enjoy much nor suffer much, because they in the gray twilight that knows nor victory nor defeat.

What though strength fails? Boldness is certain to win praise. In mighty enterprises, it is enough to have had the determination.

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

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.

Obstacles don’t have to stop you. If you run into a wall, don’t turn around and give up. Figure out how to climb it, go through it, or work around it.

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.

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.

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

Continuous effort — not strength or intelligence — is the key to unlocking our potential.

You have to be burning with an idea, or a problem, or a wrong that you want to right. If you're not passionate enough from the start, you'll never stick it out.

Never give in, never give in, never, never, never, never-in nothing great or small, large or petty, never give in except to convictions of honour and good sense. Never yield to force; never yield to the apparently overwhelming might of the enemy.

Four steps to achievement: Plan purposefully. Prepare prayerfully. Proceed positively. Pursue persistently.

The secret of success is conviction and persistence.

Abandon the idea that you are ever going to finish. Lose track of the 400 pages and write just one page for each day; it helps. Then, when it gets finished, you are always surprised.

Real excellence does not come cheaply. A certain price must be paid in terms of practice, patience, and persistence—natural ability notwithstanding.

Never give up on what you really want to do. The person with big dreams is more powerful than one with all the facts.

We can do anything we want to if we stick to it long enough.

To remain indifferent to the challenges we face is indefensible. If the goal is noble, whether or not it is realized within our lifetime is largely irrelevant. What we must do therefore is to strive and persevere and never give up.
