While we can wield our might to be as strong and as resilient as we can be, some people need that extra nudge to build their resilience. For instance, if one grows up in a household where his parents are verbally abusive, it might take him a lot more effort to fight his inner demons (i.e. being self-critical, low self-esteem, etc.) than someone who's confident having grown up in a health household.
Of course, like what @maitatoy
has mentioend - resilience is a muscle that we need to flex! It's just that we have to acknowledge some people are born to be more athletic than others.
