I do think that gamblers who take gambling activities seriously have their motivation come from the amount  they envision and hope to win, hence why they remain persistent in gambling instead of quitting after winning a little.

A gambler with a winning amount in mind, gambles much more and can become easily addicted than a gambler just gambling for fun and without a particular winning amount in mind.

In essence the thought process a gambler focuses on during any gambling activities will determine if such a gambler would gamble much more or lesser than normal and also, if such a gambler would become successful at their gambling endeavors.

What are your thoughts?
