Men who have nothing to lose never give a thought for eternal life.

Anyone who loves in the expectation of being loved in return is wasting their time.

Whenever you want to achieve something, keep your eyes open, concentrate and make sure you know exactly what it is you want. No one can hit their target with their eyes closed.

Man needs what's worst in him in order to achieve what's best in him.

There are two kinds of idiots - those who don't take action because they have received a threat, and those who think they are taking action because they have issued a threat.

Love, too, was just a question of time

Because you believed I was capable of behaving decently, I did.

And one more thing: you still believe that man can be good. If that weren't the case, you wouldn't have invented all this nonsense to convince yourself otherwise.

They were so ignorant, so naive, so resigned to their lot. They refused to believe anything that didn't fit in with what they were used to believing.

Even God has a hell: his love of Mankind.

Evil would never bring Good, however much they wanted to believe that it would. By the time they discovered the truth, it would be too late.

Pure love is an unmediated, unmitigated, and unrevealing, but everlasting source of joy for the giver and for the receiver.

Those who think, Present.

At one time it really felt like forever might happen for us.

He who has gone, so we but cherish his memory, abides with us, more potent, nay, more present than the living man.

I have not been an easygoing guy. I think it's called bipolar manic depression. I've got a rich history of that in my family.

I don't sleep much. It takes me a long time to fall asleep. I'm a bit of an insomniac but, when I fall asleep, I don't ever want to wake up.

Animals are unpredictable things, and so our life is unpredictable. It's a long tale of little triumphs and disasters and you've got to really like it to stick it.

I hate reality shows that are not reality.

I can’t think of anyone else I’d travel around the universe with than Amy Pond.

But you only get so many do-overs in this life, so many chances to, if not change your past, alter your future.
