Optimism

Optimism makes you less likely to walk away while not actually increasing your chances of success. That means that being overly optimistic will make you stick to things longer that aren’t worthwhile. Better to be well calibrated. Life’s too short to spend your time on opportunities that are no longer worthwhile.

“Above all, do not lose your desire to walk: Every day I walk myself into a state of well-being and walk away from every illness; I have walked myself into my best thoughts, and I know of no thought so burdensome that one cannot walk away from it.” — Søren Kierkegaard

in times of intense stress or adversity, future-oriented thinking such as hope may be more effective than mindfulness in sustaining positive mindsets and action-oriented outcomes such as engagement.
