It is a very poisonous structure to put yourself in to play a recreational lucrative hobby as a job/life. The cash games are revenue based/percentages based/ high-frequency rake. On top of that the edge in NLH is like non-existent now a days. The game is extremely stressful if bad variance comes your way it will ruin your mood for life, your income your livelihood and basically your Psyche will be dependent on a game with like no edge and notoriously wicked variance.
If you are a marketable pro it is a good idea but if you are not you have terrible
odds to compete against on top of that you have to play self employment tax,
gambling income tax bracket etc. expenses. I suspect it is a type of hell more stressful than business stock trading.
