If there is one sin—or rather one waste—it is not doing what you have the inclination or gift for.

It doesn’t matter how long you live on planet earth, if by the time your whole life has evaporated, you have not solved the problems you were created to solve, then you wasted your life.

Do not waste time for that is equal to wasting life.

The only thing you have to show for a wasted or spent time is that you just realize that you are getting older.

But once, in his anger, Aidan had asked me whether I thought I had wasted my life, and I had told him no. No, I had not. But I had been wrong. And Tom Cardle has been right. For I had known everything, right from the start, and never acted on any of it. I had blocked it from my mind time and again, refused to recognize what was staring me in the face. I had said nothing when I should have spoken out, convincing myself that I was a man of higher character. I had been complicit in all their crimes, and people had suffered because of me. I had wasted my life. I had wasted every moment of my life. And the final irony was that it had taken a convicted pedophile to show me that in my silence, I was just as guilty as the rest of them.

Any life wasted or spent is gone and it will never come back.

Doubt as sin. — Christianity has done its utmost to close the circle and declared even doubt to be sin. One is supposed to be cast into belief without reason, by a miracle, and from then on to swim in it as in the brightest and least ambiguous of elements: even a glance towards land, even the thought that one perhaps exists for something else as well as swimming, even the slightest impulse of our amphibious nature — is sin! And notice that all this means that the foundation of belief and all reflection on its origin is likewise excluded as sinful. What is wanted are blindness and intoxication and an eternal song over the waves in which reason has drowned.

An unhappy life is a wasted life.

To own something and not be aware of it could not only be annoying, but fatal too. That is why most people had all the time but did nothing with it. They died leaving behind no invention or product that they could be remembered for.

Every man has been called to produce a certain number of products within the time allocated to him to live on earth and failure to hit the target would mean a wasted life.
