A gambler cannot be called an addict if he can stop at any point. Those who are addicted gamblers can never take losing easily. Even if they lose, they feel that they have to recover their lost money immediately. As a result of their misconception, they are gambling day after day. Some to recover his losses and others to win. Either way those who lose control over their gambling become addicted gamblers. There are some addicted gamblers who gamble after a loss with the intention of recovering that loss and eventually lose their entire bankroll. Those who wish to conduct normal and healthy gambling must stay away from addiction and have good money management skills.
Chasing losses in gambling is like chasing after a car that have failed brakes, you don't know where it's going to crash and when it crashes, it is going to case damage to the car and perhaps to the person driving it. A gambler must not chase losses in gambling because they will not recover the lost money, they will still loss more. I wish I can make all addicted gamblers to know this.
Think of a way of making it happen, maybe a long term thought. However, what you do here is also an awareness and some new players will get to read your idea. However chasing after losses doesn't signify having a good gambling management skill. Most players don't, by any means, bother about a better gambling habit. Sure lots of players still possess self control and the ability to stop playing whenever possible. Also it's vital to add a habit that promotes financial management.
Like what Op briefly stressed upon, playing with the amount we've won and reserving our capital. Gambling offers some funds to winners to keep on playing in the casino. But this benevolent attitude affects negatively the thoughts of the player, and challenges him to wager more to win big. Those wins are meant to be managed, instead of rushing to end it on same session. I recommend stopping once the designated time for the session, set by us, is exhausted. The extra funds can be used to enjoy enough of the next session, probably, they'll be more wins. The most vital aspect of it is being able to enjoy the game.
