How Can I Contribute to the Ethereum Ecosystem?

I'm new to Ethereum, and have done solid amounts of research into it, but a majority of content that I see here is associated with stocks, trading, etc. While that is something I'm interested in, I'm determined to be in this space for the long haul and don't want to focus on just the economics of it.

That said, what are some good ways to contribute value to Ethereum long-term?

Also, I'm a digital artist and looking into CryptoArt/NFTs, so some peripheral insight there would be stellar as well.

Thanks!
