Walk away. Take a break. You won't miss that big sure thing, theres always next week or next month.
Its refreshing as hell and easy to do. Stop the chase.
The weird thing is that stopping is a rush in itself! You appreciate the amount of stress that you were under when you were betting. Its very relaxing. I periodically stop. No TV, no newspaper, no forum. Just me and walking down by the Lake, doing shit around the house. Its great.
Been gambling for over 35 years, longevity is probably due to the vacations as I like to call them plus I bet to make money, not for the rush. Betting is very stressful, I rarely watch the games now not good for the heart, a take a peek see how its doing, if I'm winning my bet by miles then I'll watch, if its too close I'll look a the scores after all is said and done.
