The TRUE test of a counter...
...is not how fast he counts down a deck, how many indices he knows, or how well he plays - it's how much he ENJOYS to play. It's how much he enjoys being at the tables. It's how much he YEARNS to read every book ever written on the subject. This is what seperates the counters from the ploppies. Counters have an instinctive desire that promotes an enormous level of dedication to this game.
Let's face it, there are a million better ways to earn money out there. Was is Wong who said "Anybody out there smart enough to do this is probably making much better money doing something else"? The reason we all play blackjack is because it's fun for us. If it is no longer fun for you, then by all means stop. If you're anything like me, a year or so from now you will be reading through your old blackjack books again, remembering your past sessions, and itching to get back on the soft felt.
If not, then walk away and don't look back. If you can go on without ever missing it, that means you never really wanted it in the first place. At least you got a taste of this world. You should always feel proud that you learned how to beat the house, even if you never got a chance to.
If we never hear from you again, good luck. If you ever do come back, you'll have plenty of friends waiting for you. (Joint bankrolls maybe? Sorry, I can't stop thinking about blackajack for 3 minutes!).
