Your decisions WILL matter in any games you play against other people.
Consider only one thing: Is this the best decision I can make given the cards I've been dealt? Can I make a better choice? If you can't make up your mind, you're not thinking hard enough. When the scale appears to be balanced, consider more factors.
When something bad happens, most people have a lot of excuses. They blame their loss on luck, teammates, the environment, not feeling well, or anything other than themselves. Yes, if you're a mediocre player, you can make all the excuses you want. Excuses, however, no longer matter if you want to win above a certain level. Excuses such as "that's not easy," "it doesn't seem fair," or even "I can't do that" are completely useless. How will they assist you in improving your game? They simply cannot! All that matters is that you learn from your mistakes and take extra precautions to avoid them happening again.
In the end, your opponents can do whatever they want, but you get to choose how you respond. As a result, you are solely responsible for your own choices and decisions. Be humble, grateful, accountable, and don't blame others. If your decision was a mistake, learn from it.
Proactive people, according to Stephen Covey, "do not blame circumstances, conditions, or conditioning for their behavior." When we take responsibility for our choices, our lives are no longer left to chance. We can take the wheel and go wherever we want. Do not allow other people or external circumstances to control our lives.
Simply put, don't make excuses.
Another critical point to remember is that the outcome does not indicate the quality of a decision. You make the best decision you can based on what you know, but its success is heavily influenced by
(a) relevant information you may lack and
(b) luck or randomness.
Well-thought-out decisions may fail as a result of these two factors, while poor decisions may succeed. Recognize whether your win or loss is due to the quality of your decision or luck to be a consistent winner.
Each game's outcome provides immediate feedback on how your decisions are faring. However, it is a tricky type of feedback because winning and losing are only loose indicators of decision quality. You can win lucky games and lose unlucky ones.
It is not the outcome of a decision that makes it great. A good process leads to a good decision, and that process must include an attempt to accurately represent our own state of knowledge. That, in turn, is some variation of "I'm not sure."
We are taught not to say "I don't know" or "I'm not sure." These expressions strike us as ambiguous, unhelpful, and even evasive. However, becoming comfortable with the phrase "I'm not sure" is an important step toward becoming a better decision-maker. We must accept our lack of knowledge.
What good decision-makers and game players have in common is a comfort with the world being an uncertain and unpredictable place. They understand that they can never be certain of how something will turn out. They embrace uncertainty and, rather than focusing on certainty, they try to determine how uncertain they are, estimating the likelihood of various outcomes.
Understand that improving decision quality does not guarantee wins, but it does increase our chances of winning. In the long run, an expert player with better decision-making skills will always outperform the novice.
The future is uncertain, but you should never leave anything to chance. Always strive to make better decisions.
