Hello, I sometimes regret dropping cards, but it's not that bad! I usually think what decision I make, and I believe that every decision I make at the time of its adoption is always correct! I generally try not to be upset about poker a lot, because even if you do everything right, luck may not turn in your direction and you will still lose! I try to control my emotions, because a lot depends on them in poker! I wish you a lot not to get upset and always only enjoy playing poker! Good luck!
