Running a ethereum node without staking

I am planning of running a ethereum node, I have all the resources except eth, But I learnt today that I can run a node without having 32 ETH. But my question is what will I earn from running a node? Is there any financial benefit to it. If I anybody is running, mind sharing your thoughts on it?

Although I am still fine to run even if I don't make any eth(just wanted to contribute to decentralization) but just wanted to know what are the pros and cons of running a node without staking.

​

Thanks!
