@octopus Python, Javascript, C#
Learnt the first 2 years ago for gamedev stuff, JS was the one that stuck. Bounced off C# multiple times, only learnt rudimentary Python stuff, but the principles stuck around.
My motivation tends to be project-driven, and learning in abstract from working on the actual project tends to be difficult to focus on, but you can't "just dive in and learn from your mistakes" in this sort of thing. So is tricky.
