Got a proper job at 28. Gave it up to try comedy at 38. Decided to get fit and healthy at 48. It's never too late. But do it now

A world without any lies at all is not a good world, because it's artless and because there are no white lies, no flattery.

Life is just a series of peaks and troughs. And you don't know whether you're in a trough until you're climbing out, or on a peak until you're coming down. And that's it you know, you never know what's round the corner. But it's all good. "If you want the rainbow, you've gotta put up with the rain." Do you know which "philosopher" said that? Dolly Parton. And people say she's just a big pair of tits.

Science seeks the truth. And it does not discriminate. For better or worse it finds things out. Science is humble. It knows what it knows and it knows what it doesn’t know. It bases its conclusions and beliefs on hard evidence -­- evidence that is constantly updated and upgraded. It doesn’t get offended when new facts come along. It embraces the body of knowledge. It doesn’t hold on to medieval practices because they are tradition.

People think "The Office" was improvised, but it's all on the page. We do that because what we found is that in the early days of "The Office," we went in with it sort of 80 percent scripted and we did some things and then we improv'd and we did - you know, and it gets a laugh on the floor because it's the first time they've heard it.

That’s the other thing I learned that day, that the truth, however shocking or uncomfortable, in the end leads to liberation and dignity.

Comedy and drama are different sides of the same coin. And the thing about comedy and drama is about likability. It's about character first. It's about story. And for me, it's about empathy, and I think the realer someone is, the further you can go either way with them.
