I just received a mail from Princeton regarding my waitlisting status for their math cohort! Not rejected, but actually waitlisted! Do you think this is an appropriate honour for college applications or is it not worth mentioning later on?

Hi everyone! My name is Abi and I'm aspiring to get into a good college in the US with a full-ride scholarship. I have started working on my portfolio and am the founder of an initiative called "The Introverted Reader". If anyone is interested, please comment below so I can give you the link. One of the main challenges I am facing right now is time management. I am part of many ECS but at the same time am prepping for University level examinations in case the US college dream doesn't happen. So it's kind of hard to focus on both. Any tips?
