The song "Shake It Off" by Taylor Swift is about learning to let go of other people's opinions and living your own life. Despite what other people may say and do, she encourages listeners to keep going, have faith, and move on. By "shaking it off", she is telling people to not let the opinions of others stop them from chasing their dreams and embracing who they are. In the end, the chorus encourages people to "just shake it off" and not be affected by the actions of those around them.
