Why are you quitting? IF you dont enjoy it then fair enough. If your new job means you have no more time then thats a real shame. You seem to have put quite alot of effort into improving and that makes me think you enjoy at least some of it so I hope you get enough time to play occasionally. You dont have to play every day or even every week to keep poker up as a hobby.
Anyway goodluck for your non-poker stuff and make sure you keep checking in.

btw the party isnt over yet. Everyones just taking a short vomit break. Itll all be going smoothly again soon
