Foresight. Chess is based on planning, strategy, and tactics. This requires trying to predict and analyze the future.
Circumspection. It's important to anticipate threats, which sometimes come from surprising places.
Deliberation. It's easy to spoil hours of effort with one hasty move. So it's important to think carefully and check your analysis (to the extent that is possible while also keeping in mind the time constraints).
Hope and perseverance. Many chess games have a lot of ups and downs. Determination and patience (rather than panic), even in positions that seem bad, can often succeed.
