Hi Michelle, good luck on Steem!
My advice would be to see this as a long-term thing - you won't get rich overnight, so don't fall into the trap of chasing money, then giving up when it doesn't happen.
If you can invest some money into the platform, you'll get a head-start, but it's all about sharing what you love, being part of the community and attracting an audience who loves your work (as Steem grows, there'll definitely be a tribe out there with your name on it).
Anyway, have fun, and good luck.
