Hey @elsteemo! Welcome to community! It takes time to start earning on this platform, but you can surely do it without investment (although it would help). They beauty of STEEM is that it's a whole ecosystem, not just steemit.com, so take your time to explore projects like Uotipan.io , d.tube , dsound.audio and so on. Good luck!
I have only heard of d tube out of those so I have so learning to do for sure...
