What is the skill/talent you have that you get praised for but you fiercely keep as an hobby/interest with no plans to expand on it?

I don't mean I'm better at them than everyone else, it's just that two of them are things people do sometimes nag me to do professionally, as per OP's question.

I find saying "so what, I'm good at sex too, doesn't mean I have to be a sex worker" gets my point across and stops the nagging, because that's something many people only enjoy as a hobby.
