If you treat steemit like an ATM machine you will never earn anything. If you want to actually earn enough to feed yourself you need to take your time and build up your account first. Coming here and trying to pull money from day 1 without making any sort of investment in your steemit business is an instant plan for failure.
Make no mistake if you want to earn money to pay bills then it's a business for you. Businesses take investment in time and money.
There are plenty of posts out there teaching you what needs to be done to grow a successful account on steemit, but they will all require you to do some work.
I would think you would be much better off doing this in a way that gives yourself 6 months to grow your account and then start trying to buy groceries with the money. That really isn't enough time to build much, but at least you can focus on building a following which might be able to give you enough votes to pull off what you are hoping to achieve. It would be a fair test at least.
