Not nearly enough, unfortunately. I spend a fair amount of time on here, but usually not in a deeply studying manner. I should do that more and get more involved in HA more often than I do. I tend to get bogged down in routine stuff, or spend time answering others questions that are often pretty easy stuff that they should know anyway. But, everybodys gotta start somewhere, so I don't mind that so much, but it does take time.
Outside if that, I'm just now getting back into my reading, or re-reading actually. I'm trying to set aside an hour a day for that, certainly no less than 30 min.
Analyzing my own hands/db away from the game is something that I spend far, far too little time on, and I really need to work on that. I can't remember the last time I actually analyzed any of my own hands/sessions.
I think I'm kind-of a victim of being satisfied with my game atm. Which is a bad thing 'cause if you're not learning and studying; you're falling behind.
