"I must be careful not to get trapped in the past. That's why I tend to forget my songs"

In this quote, Mick Jagger is expressing the value of not home on the past. He acknowledges that it can be simple to get caught up in memories and nostalgia, however he understands the risk of ending up being trapped in them. Jagger thinks that in order to move on and continue developing, he should let go of the past and concentrate on the present. This is why he tends to forget his songs, as he doesn't wish to be tied down by old concepts and instead wants to constantly develop and develop new music. Jagger's words work as a tip to not let the previous hold us back, but to embrace the present and look towards the future.
