"Stronger" by Everly et al. gives concrete ideas on becoming more resilient. Here are a few quotes:
“Taking personal responsibility requires courage, perhaps more courage than being decisive. After all, most of us believe that mistakes are who we are, rather than what we did."
“Resilience is the ability to personally rebound from adversity.”
“Optimism is more than a belief, it’s a mandate for change.”
“It is never too late to be what you might have been.” –George Eliot
“We suggest that the moral compass for resilience consists of four points-honesty, integrity, fidelity, and ethical behavior.”
Resilience starts with character. It flows through attitude, action, and persistence (tenacity) and is supplemented with interpersonal support of mentors, coaches, and teams.
