Hell yeah! You are not alone in replacing some of your old fiat income with freelance steem income. The hard part for me is the fluctuations... it's tough to rely on steem when the price could be $1.50 or $0.75 two months from now and I have no idea which it will be.
That's why I have been working to find a balance, earn maybe 30% of my income from steems, and the rest elsewhere... Good stuff.
