Like any business you need working capital, or a
bankroll to fall back on for downswings. I would say you need to have 50-100 BBs of bankroll, and about 6 months of living expenses saved before you could even consider quitting your day job. What does that look like?
For me, if my wife and I were to divorce. For me to cover bills I would need about 2.2K-3K a month depending if I kept the house or not. 13.2K-18K in personal savings....
I'm making about 4K a month currently with everything I do. Since I can realisticly make about 5-7BBs per hour on avg. Without doing the math means that I would have to grind 1000NL 40 hour weeks to keep up with my income now. So I would need about 15K in my personal savings, and 50-100K in my working capital or bankroll to strictly play and keep the same level of income I currently have. Assuming there was a 1000NL game avaliable to play for 40 hours a week.
