Art dream vs stable healthcare job? — realistic advice needed

I’m from a low‑income family in Hong Kong. My biggest dream is to become a director or singer, but I know art barely makes money here.

I’m really scared. I can’t rely on my family financially, and I worry I won’t even be able to feed myself if I chase art full‑time right now.

I’m planning to study a 2‑year higher diploma to become an X‑ray/MRI assistant for stable income (around HK$27k‑35k per month).
Should I get this stable job first to survive, then pursue my art dream part‑time?
Or should I risk everything for art?

I need real, honest advice, no sugar‑coati
