Starting my SIP journey with ₹20k/month. Is my plan too aggressive or just right?

Hey everyone, I’m 21 and finally in a position where I can start investing ₹20k every month. Since I’m young, I have a long-term horizon (7–10+ years), but I’d say my risk appetite is moderate I don't want to go "all-in" on high risk, but I want decent growth.

Right now, I’m looking at a mix of Midcap and Multicap funds for the equity side. I’m also thinking of adding some Gold/Silver to the mix just to keep things balanced and safe for the long run.
