[WWYD] If you could magically acquire a new skill with no effort, what would it be?

Skill on able to travel back to the past and future

The skill to know when someone is lying, especially when they are selling me insurance. 🌚​​​

Able to master multiple languages

I would want to acquire the skill of learning how to learn.

Armed with that, I would go on to develop deep and specific knowledge.

I wished that would be effortless but in reality, it's probably quite the opposite - it's gonna take real effort: money, time, discipline and focus.

If it's a party trick, I'd say magic!
