If you could instantly master one of these skills, which would you choose?

I would love to be adept at all four skills. Previously I learned to play the piano, the guitar and the violin but was never proficient at any of them.

i have previously learnt French and Spanish but again only to a basic level.

i find public speaking terrifying but i have spoken at large events

I have never tried coding but understand how important it can be and if I had to choose between all four I think coding would be the most useful in today’s modern world
