"In My Life" is a song by the British rock band The Beatles, composed by band members John Lennon and Paul McCartney. The song was originally written by John Lennon, Paul McCartney also contributed to the final version of the song, and Paul's contribution is still debated. George Martin contributed the instrumental part of the song. The song was released on the band's 1965 album "Rubber Soul" and ranked 23rd in "The 500 Greatest Songs of All Time" in Rolling Stone Magazine.

At that time, the "Beatles" wanted to make an album about childhood. This idea originated from a long poem about the past life by Lennon.

The lyrics of this song describe Lennon's bus journey from home to the dock. After a long journey through Liverpool, he captured what he saw and heard along the way. However, after writing, Lennon felt that the lyrics were too long and boring, like a diary with a line drawing. So he decided to make the lyrics more resonant with people, so he changed the theme to look back on the past in a broader sense: Nostalgia for lost childhood and old friends.

The lyrics turned around later-Lennon told people that the past was not the best. This is actually a love song. What Lennon wants to say is that although he has a deep love for the past, he loves her even more. This turning point makes the song more positive and mature.

Lennon once said: "This is the first time I have consciously written about my life. Before, we only wrote some popular songs without too deep thinking; we only wrote songs to make a sound. No connection. I think this song is my first important work."
