I felt so guilty when, in the first few months of my entering gambling at casinos, I had lost $7,000 of my savings. I couldn't fathom it. I was raised to be responsible with money. But ... I felt like I had to get it back, and that meant gambling more, trying to master blackjack and do it better. So . . . three years and three months later, when I finally stopped, and I had lost many times more that $7,000. I just wish that I had forgiven myself at the beginning, and moved away from this pastime.
Let it go, folks. Chasing losses is degrading your unique self-worth. You are worth far more than that money! You are not likely to win it back anyway, and even if you do, you are highly unlikely to quit after winning.
