Your Success will All Depend on Your Motivation
Like anything else in life, you get out what you put in.
Recreational bj is something many do and why not want to win while doing it? Makes sense to me. To learn basic strategy and a sound counting system is something that will take time, but remember, it's like riding a bike or learning your multiplication tables, once you know it, you know it. Only have to work hard once.
I think Wendell was speaking of KO and with KO you don't need to worry about true counting as that's the main reason most people learn KO...so they don't have to TC.
As for losing sessions. Get over the idea you won't have major losing sessions. It's gonna happen...and OFTEN!
Counting is NOT a magic formula that allows unlimited withdrawals from the casino. It don't work that way. You will have a small edge, at best. You have to be able to stomach the ups and downs as there will be many of both.
What you will find, though if you are doing it correctly...over a period of time where you get a good number of hours in, your win/loss graph will show ups and downs, but the graph will slowly rise as time goes on.
You have to think in long terms and not "sessions". Your play is one continually long "session" over months and years of play. Only then can you really determine whether you are a winning player and whether or not all that time you devoted to learning was worth it.
Good cards,
