[Central Limit]

You didn't really give much info about the limits you play.

Also, in my opinion, the relevant equation is:

job + poker > poker only

Let's say you make 100k/year playing poker 20 hours/week and you make 100k/year working 40 hours/week. Of this, you manage to save 80k/year directly into your bankroll. What I predict will happen is the following:

When you go poker only, you'll play 50 hours/week. You'll make $150,000/year*. But you'll have to pay your own health insurance, won't have a 401k, may have to file taxes as a professional poker player. So, you'll end up saving about $20k/year to your poker bankroll after all this. Based on this, it's usually better for your life and your poker if you keep your job.

* Why only $150,000/year when you're tripling the amount of poker you're playing? Lots of reasons. First, you currently plying mostly on the weekends. The games are easier on the weekends. You won't be able to maintain your winrates during the week. Also, it's rare that you can maintain your A game for 50 hours. It just gets too draining. And on and on.
