Fear is an emotion, you meant, right? But fear, if well organized and knowing how to use it, can be used to our advantage; it should not be a burden.
Gambling is personal, each person must know their own pace of play and only they will know when to stop playing and when to continue, and if so, as long as there is money to fill the bankroll. The biggest challenge is to make this bankroll grow, to win more than to lose.
Achieving what you said relies on the player's strength to save his funds. How will a player win more than he's lost in gambling? Saving money for another gambling session is in the player's jurisdiction. Winning or losing is under the control of the casino. And I wouldn't dare to manipulate it.
