Both. Two different definitions of the same word. One being physical strength, the other mental strength/strength of character.
the strength to not pick up a gun and blow your brains out
strength can be physical, but it can also be mental; strength can be the ability to let go, to live, to move forward, to progress ahead with your dreams even when others want to crush them completely; strength could also be standing for something you believe in, even though you're still afraid.
you're welcome; I don't look up definitions of words, I like to analyze things myself.
great, then I'm getting there
