You might not be a counter if

If you think advantage play is unfair to the casino.

You hope you don't get arrested for illegally counting.

If, after a winning session, you give (or tip) the money back to the casino because you feel that you did something wrong.

Yeah, but I always HAVE to go to the bathroom at the wrong time! Am I supposed to piss my pants just because the count is good?

It depends (no pun intended). If the count is high enough you may want to push your limits. At the start of each shoe you need to ask yourself 2 key questions. If you answer either as no you should not start a fresh shoe.
1) Do you have enough money to last through a great shoe in which you lose all your bets?
2) Can your bladder last until the next shuffle?

The idea is the last thing you want to have happen is to have to walk away from a great advantage situation. Whether number 1 or number 2 the affect is the same (again no pun intended) you can't play through a high advantage shoe without the possibility of having to go (again no pun intended). Okay the last 1 was intended.

It's a good way to clear the table.
