If you were raised on candy, you wouldn’t truly understand how sweet it is unless you also tasted bitter and sour (you would also likely get diabetes and die young).
Life is like candy. The difficult, bitter experiences we encounter allow us to appreciate the bits of sweetness that we also experience. Being grateful for those things that teach us what sweetness is (difficult as I know that can be) can put you on a path of living a more nectarous life. (Yeah. I just used the word “nectarous”.)
