There's a popular  remark among gamblers in the part of  my country I reside. The saying is expressed like this "if you quit that's when you lose".  They use this statement to encourage and give futuristic hope to themselves that no matter how much they loss today or how many wagers they have lost they don't need to quit as it's possible you may be the next jackpot winner tomorrow. For it's like say don't quit yet there may be a light at the end of the tunnel.

From what I observed from this statement is that, many of these gamblers have been misled by this very remark of a hypothetical hope which has liquidated their account.  While some who would have quit gambling long ago still hedge their hope on the idea behind the statement and keeps wagering.

Now let's take this to a discuss; how correct is this statement? And is there any similar statement like that in your home-country that's popularly used among gamblers to encourage themselves from quiting gambling because they're losing?
Or would you allow your decision to quit gambling to be affected by any popular statement among your fellow gamblers or it's a no no thing for you?
