For me it is normal specially if the amount that we lose isn't a small amount or just a couple dollars.
I usually feel like staying out or laying low after losing a good amount of money, but if it is just a couple of dollars I would still continue to play or bet.
You're right about that, when I was a novice, I had those fears, obviously because I did everything that one should do, I did it , so in view of this, I am a person who now does not feel even the slightest fear of losing, because it is as you say , I only lose a little and I do not allow myself to lose amounts that will damage my overall economy.
