The bigger question might be, will anyone know what "on fleek" means in ten years time? And more to the point, does anyone know now?!
The pregnant reality star was filmed penning the note to 44-year-old Kim for Glamour US, revealing her hopes for the future.
In true Kim style, she focused on a mixture of heartwarming and humorous topics, including family, contouring and the future of the selfie.
After revealing she still hopes to feel at ease with her fabulous body, Kim moved on to her now 12-year-old daughter North, saying: "I hope you remember that preteens are going through a lot. I know junior high is really tough so remember to have a lot of patience."
Kim then turned to her sisters, hoping Khloe "finds her happily ever after and falls madly in love because she really deserves it." For eldest sister Kourtney, Kim hoped she'd be "maybe done with having babies."
"I hope Kendall will continue to be modelling and doing whatever she wants to do." And youngest sister Kylie "better be doing whatever she wants because she's not usually one to take any direction."
Kim then focused on what she hopes to retain..."I trust that you will still be the queen of contouring." And also had some brave new ideas for scientists, hoping that someone would "invent a mysterious and delicious green juice to keep you tan forever."
In the year 2025 Kim also hopes she'll be continuing to ignore haters and call her mum, Kris Jenner, every single day. Aww.
Kim ended with a barrage of crucial questions: "Are you still filming Keeping up With The Kardashians? Are you still decorating our dream home? Are selfies still a thing? Are the terms 'bae' and 'on fleek' so 2015? If not, am I still on fleek?"
Whether selfies are a 'thing' or not, we're pretty sure Kim will still be taking them!
The reality star ended on a very important note: "If you haven't broken the hundred billion mark on Instagram followers, I'll be very disappointed in you. Bible."
