I know we all wanted to win but Don't ever think that in gambling you'll always win nor to always loose. You'll wonder why you always lose rather than to win it is that will matter on your strategies, but not it depends only, luck is what we need for in every time we gamble.
Don't make yourself becoming a master of all because it is really impossible especially in gambling. Believe me or not, you can't actually win over the house. Some had lost while someone had also won, that is the reality gambling but unfortunately, we can' t have luck all the time that is why we suffered losses sometimes always.
