I believe that perfection is not attainable, but by chasing perfection, we can reach excellence.

For it is always true that to whatever point the perfecting of anything leads us, progress is an approach towards this point.

We're forever teetering on the brink of the unknowable, and trying to understand what can't be understood.

Perfection is what you are striving for, but perfection is an impossibility. However, striving for perfection is not an impossibility. Do the best you can under the conditions that exist. That is what counts.

We must never forget that we are bound toward perfection and should aim ceaselessly at it.

Perfection may be unattainable, but in our pursuit of it, we can grasp excellence.

Not perfection as a final goal, but the ever-enduring process of perfecting, maturing, refining is the aim of living.

Gentlemen, we will chase perfection, and we will chase it relentlessly, knowing all the while we can never attain it. But along the way, we shall catch excellence.

Yet no matter how much better we get, we’ll always have hard work to do, we’ll never be done, and we’ll never get it right.

Happiness is a constant work-in-progress, because solving problems is a constant work-in-progress.

Perfection is something we should all strive for. It's a duty and a joy to perfect one's nature... The most difficult thing is love. A loveless, driving person that just competes in the rat race is far from perfection in my book.

Gentlemen, we are going to relentlessly chase perfection, knowing full well we will not catch it, because nothing is perfect, but we are going to relentlessly chase it, because in the process we will catch excellence. I'm not remotely interested in just being good.

It is true that we shall not be able to reach perfection, but in our struggle toward it we shall strengthen our characters and give stability to our ideas, so that, whilst ever advancing calmly in the same direction, we shall be rendered capable of applying the faculties with which we have been gifted to the best possible account.

Many of you have already found out, and others will find out in the course of their lives, that truth eludes us if we do not concentrate our attention totally on it's pursuit. But even while it eludes us, the illusion of knowing it still lingers and leads to many misunderstandings. Also, truth seldom is pleasant; it is almost invariably bitter.
