If I could master any skill instantly, it would have to be the ability to learn languages. I’m not a natural linguist, I was more into science and English at school and struggled with the language lessons. I think partly because I was worried about embarrassing myself by making a mistake. I used to get really nervous about having to speak aloud, which now I think is really stupid; but when you’re at that age, everything feels like life and death.
The only language I did really enjoy was Latin, ironic since it’s a dead language; but the lessons were really interesting and there seemed to be logic behind the way the sentences are/were formed. It’s probably the same for all languages; but I guess it depends on how you are taught. Latin seemed to be a lot of analysing what was written down and picking up the pronunciation from reading aloud, as opposed to having to pick it up from listening to the teacher. I guess I learn better when things are written down.
So if I could have the ability to instantly master any language I would really love to be able to do that. It would make travelling a lot easier!
