“Giving up smoking is the easiest thing in the world. I know because I've done it thousands of times.”

“It's easy to quit smoking. I've done it hundreds of times ”

Mark Twain (1835–1910) American author and humorist

“The world's most funniest and easiest thing is to give an advice…”

Chetan Bhagat (1974) Indian author, born 1974

“I did think about giving up smoking, but I decided not to, because I'm not a quitter. And I know that every cigarette I smoke takes five minutes off my life, but I also know it takes ten minutes to smoke it. That's a clear five-minute net gain, I reckon.”

Ed Byrne (1972) Irish comedian

“I think I've made a lot of sacrifices. I work very, very hard. I've created thousands and thousands of jobs, tens of thousands of jobs, built great structures. I've done, I've had tremendous success. I think I've done a lot. … I think they're sacrifices. I think when I can employ thousands and thousands of people, take care of their education, take care of so many things, even in military. I mean, I was very responsible, along with a group of people, for getting the Vietnam Memorial built in downtown Manhattan, which to this day people thank me for.”

Donald J. Trump (1946) 45th President of the United States of America

“I've stopped smoking… I think the cost was a lot of it, and not being able to breathe. I first gave up smoking when I was eight.”

Dave Allen (1936–2005) Irish comedian and satirist

“Done time in the lock-up, done time on the streets. Done time on the upswing, and time in defeat. I know what I'm askin'. I know it's a lot. Just to say that I love you. Believe it or not.”

Jerry Garcia (1942–1995) American musician and member of the Grateful Dead

“I love to smoke. I smoke seven thousand packs a day!”

Denis Leary (1957) American actor and comedian

“I've always considered myself a failure: I feel I've never done anything wholly right. […] Everybody will tell you, "Oh no, how can you say that, because ten thousand people clap you on a night?" But part of that is reflex action and part of it is because you're reasonably good. But if you're great, that's a different thing.”

Ronnie Drew (1934–2008) Irish musician

“Spiritual realization is theoretically the easiest thing and in practice the most difficult thing there is. It is the easiest because it is enough to think of God. It is the most difficult because human nature is forgetfulness of God.”

Frithjof Schuon (1907–1998) Swiss philosopher
