This is a trick question that can only logically have one answer. It’s more of a logic / linguistic test than a prompt.

First of all, it can’t be a skill that one has, is secret, and that one blabs about on the internet.

So, the only “secret skill” that one could discuss wishing that one had on the worldwide web must be the ability to keep a secret.

Not really a problem area for me as, being a introvert, I’m pretty tight lipped by nature.
