1. What has happened in the past.
Do not dwell on your mistakes; each hand is new, and you have to come at each one with the same mindset in order to win.
2. What the other players are saying.
Sometimes the other players will tell you that you are stupid either for hitting or not hitting on certain card combinations. Do not listen to them. Stick to your own plan and let them lose with theirs.
3. What could happen in the future.
Do not take a risk and tell yourself that you will win it back later. Take a risk only when it is a calculated one for the hand in play.
4. How long it has been since you won.
Do not dwell on your losing streak. Once again, each hand is new. Do not get bogged down thinking that you cannot win and give up before you get your money back.
5. How you must be due.
By the same token, do not think that you must be due to win just because you have not recently. Blackjack online is played with a new deck each hand; the odds are always the same.
6. What the other players are thinking.
While it is true that you can learn from other players, do not just try to copy their strategies. What is to say that they know any more than you do? Have your own ideas and do your own research to learn how to win.
7. That you need to win fast.
Do not put it all on the line to win quickly. Take your time. Blackjack pays out large amounts, so you can get your money back if you are patient and wait for a good streak.
8. How much you should bet.
Do not think about this. Bet the same every time. This way you do not win small bets and lose big ones, leading to overall loss.
9. What the House has done in the past.
Has the House busted a lot? Do not think they will every time. The House can have bad luck, too. Do not just assume they will bust, or you will lose.
10. That small odds do not matter.
The odds are everything. Do not think that it is all blind luck. Play so that you have the best odds every time you Hit.
