He was a member of the Apostles' Club, his fellow-members including Tennyson, A. H. Hallam, Monckton Milnes, W. H. Thompson, Trench and James Spedding.

In the chorus, she sings: "Don’t be so hard on yourself, no / Learn to forgive, learn to let go / Everyone trips, everyone falls / So don’t be so hard on yourself, no." When asked about the story behind the song, she elaborated: "When I was meeting my publisher, managers and label and everything was happening for me, I was going through a really hard time. I had my heart broken and I was in a dark place. It was even harder because my dreams were coming true and I had to put a smile on my face every day and power through."
