Starting to invest for the first time as a young adult with a small amount. (1500$)

I am interested in some growth. I read about dividend stocks but it seems like you need to have a big capital to make any amount of cash there. I just wanna start safe but have fun seeing my stocks grow little by little. what is the general strategy if you were at my place?

I invested in Nvidia, AMD and a few other individual stocks because I believe tech market will rise for sure. But since my starting capital is so small, I wonder if I can do better right now.
