LOL, this guy sounds like me 2 years ago,
I lived in the UK on 25nl for a little while, i did it for 4 months paying £400 rent in some shitty bedsit, I played like 9- 12 hour days 10 tables at the time, it was hard paying for food and rent and other bills but i did it although i quickly realised how much of a bad idea it was lol, its not ****ing glamorous at all its just really baddd lol. You will eventually burn out and hate your life, I really think winrates are also bullshit since it can vary so much over the longrun you shouldnt make crazy plans based on your winrate its forever changing, and is dependant on so many factors.
I highly recommend you try and get to 100nl maybe 50nl you could really do it i guess on your own if you put in long hours and try and have a rakeback deal on a site liek FTP for instance, but yea man really dont rush yourself out the door try and get like 80 buyins for whatever level your goin for i used to follow the 100buyin rule but i just find that to be overkill. Plan it out its taken me 4 years but now ftp has paid out my roll is at a point where i can think about having a nice place and playing fully pro if I crush 50nl- 100nl for two months. currently semi pro work 2 days a week poker the rest
