you need to make 28 dollar per day or 833 a month , its certainly not impossible , you have to be perfect in the game you will choose and also you must have a lot emotional control and discipline , you can make 28 dollar per day playing fixed limit 0.25/0.50$ or 0.50/1$ also you can make that money if you make at least 5-6 final tables on 1$ mtts per month , i dont really know if its possible through sngs , i only played hyper turbos and i could barely make 10-20$ per day , i recommend you to find a game which make you tilt less , its very hard to cope with tilt in some games especially mtts because the variance is huge and they are very slow.
