I'm glad that you're considering the idea of raising yourself some Steem via this community. It's really not all that different from maintaining a presence on other social media outlets, aside from the fact that you should make it a habit to at least once a week check your wallet page to collect your Steem Power and Steem Dollars (which your posts earn).

If you post your work, any tutorials or the like you do, you can make yourself some pretty good amounts of currency here. It does take thirteen days to cash out Steem Power/Dollars to actual Steem, so keep that in mind when you do want to take out whatever you've earned, and it also does deduct from your Steem Power (which is basically your influence on the site), but it's still a really good way to earn currency - especially if you're not familiar with mining or don't have a set up that's powerful enough to mine with.

Again, welcome, and glad you've found another income source - it can be rough with art!
