His company is on the verge of bankruptcy. Smith come back to Las Vegas feeling sad. At that time Las Vegas was known as the capital of casinos. He had only $5,000 when he entered a casino with a depressed mind. His destiny was revealed. He earned about $27,000 with in a week. Smith come back to FedEx headquarter and invest his money on his company even though his money was not enough to run the company but with his hard work and enthusiasm he arranged to send all the parcels. in this way he established his company.
This is really a good success of smith as well as FedEx with the favor of Casino. By the way, i am not sharing it to encourage anyone to the casino.
The casino did not change his fortune, his character did, if he has a weak character since he already won a big amount then he will just continue playing and will come to think that he can win more, but that is not his mindset and his character he went back to his company and through his perseverance and hard work his company becomes a huge success.
In reality, it's so rare to make a fortune in gambling, this guy happens to know limitations in tempting luck so he stopped at the right time.
Precisely! his action changes his life and not the casino, there are people who have enough experienced and know how to take advantage with this kind of situation, maybe if he don't quit the right time all of his winnings will be back to the house, we also heard stories of those people who were unable to manage their greed, people who instead of winning ended up losing everything back including their bankroll.
It is the edge of someone who knows to value money. They can change their fate and make something good out of gambling activities.
The hardest part for a gambler when they are winning is to stop and stop at the right time, we always have in the back of our mind the thought that we need one more roll before we stop, it takes a character to stop when you want to stop and to stop when you are already winning, there's a popular saying winner never quits, but he has full control not to follow this, no wonder he's able to create a big company because of his strong character and decision making, we are always blinded by bad decision whenever we are chasing our losses.
And that saying created lots of addicted gamblers,

though seriously speaking there are gamblers who can work with their temper and able to quit with a good amount of winnings, but most are ain't capable of doing so, they will continue to try exceeding from their luck thinking that they can still have more winning streak.
Like what I mentioned above, more on your characteristics and your good judgement to stop when you already win,
Quitting in the right timing makes your gambling an enjoying and productive session.
