I'm thinking of quitting my job

[SirArthur]

I'm near your age, and have been playing online poker for a living for around 1 1/2 years.

It is so not easy. Why is this?
After about 6 months I hit a major wall due to burn out. The monotony & tedium of daily online play can not go understated.

In the past year have taken many breaks of two weeks here, 3 weeks there, I have even taken an entire month off on two occassions.
I NEED these breaks to stay fresh. If not for them, I'd go crazy.
I'm able to take these breaks because my win rate is high enough, and my BR is high enough to amply sustain myself.

My advice to you, do not do this for a living, mainly because of all the time & money you've invested in your law career.
Also, as alluded to, playing winning poker for 4 months is not nearly enough time to determine if you can do this for a living.
The advice to pursue a different focus of your law practice is an excellent one.

Good luck with whatever you decide.
