“I think about it all the time” reflects Charli’s thoughts and feelings about the future, especially regarding motherhood. She shares her uncertainties and existential questions about when or if she should take that step in her life. It’s a personal and introspective piece that explores her contemplation on this significant life choice.

In a Rolling Stone interview, Charli stated that this song was strongly inspired by one of her close friends Noonie Bao, when she had a child. She says:

It was crazy seeing her standing in the same clothes she’s always worn, but now she has this completely different perspective on life than I do. She’s not enforcing that on me; it’s just a fact. She’s not alive for the same reasons that I am now. Am I less of a woman if I don’t have a kid? Will I feel like I’ve missed out on my purpose in life? I know we’re not supposed to say that, but it’s this biological and social programming. There’s a lot of pressure on women to not talk about that stuff super openly, especially not in pop music or in music generally; we’re supposed to be sexy and free and fun and wild. My circumstance involves me making a decision and being like, ‘I’m gonna come off my birth control. I’m not gonna tour. I’m going to see what George wants to do, and then we’re gonna try for a baby. I feel like a kid; I don’t feel like I can make that decision. […] You have to make the decision — because we have a clock.
