Working on 'projects'

Has anyone else felt the urge to give your work some new meaning by giving them secret 'project' names? I feel like not only does it give that sense of like "secret scientist" escapism but also just frames your regular work in a new light!

For example, calling your diary "Project Scribe".
Learning a langauge? No, you're working on "Project Babel".
Why go for a run when you can be testing "Project Quicksilver"!

Just a fun new framing idea imo!
