John Lennon was a legend whose work and life inspire generations worldwide. As an influential singer, songwriter, and peace campaigner, he founded the Beatles – probably the first rock n’ roll band in the world.

The Beatles star, who was born in Liverpool on October 9, 1940, had his life tragically cut short when he was shot dead in Manhattan, aged 40.

He penned more than 100 songs and, together with the Beatles, sold more than 600 million albums worldwide.

Lennon knew how influential and inspiring he was, so he devoted his life to sending positive messages to the world.

His pro-peace aesthetic and revolutionary sound clearly opposed any kind of violence, and the adept lyrics and catchy tunes managed to touch the hearts of millions of fans with his message of peace.

He reached out to the whole world with his music, convincing people to speak out against what’s wrong in society and to fight for a better world.

Today, his legend lives on, and so do his thought-provoking words.

Here are some of his most thoughtful, touching and right-on quotes, which are all more poignant since his passing.

10. When I cannot sing my heart, I can only speak my mind.
