What do we think about my portfolio?

Hey all,

Little newer to investing but I plan on just keeping these 3 and calling it good.

I'm just putting money into VOO and SCHD every 2 weeks, and buying a share of HACK every month.

I also have like .08 share of NVIDIA thanks to robinhood lmao.

I know VOO is a solid choice but what do we think about my portfolio overall as far as diversification and returns over 20 – 30 years?
