bitterness

Bad writing is more than a matter of shit syntax and faulty observation; bad writing usually arises from a stubborn refusal to tell stories about what people actually do― to face the fact, let us say, that murderers sometimes help old ladies cross the street.
—  Stephen King
You should be angry. You must not be bitter. Bitterness is like cancer. It eats upon the host. It doesn’t do anything to the object of its displeasure. So use that anger. You write it. You paint it. You dance it. You march it. You vote it. You do everything about it. You talk it. Never stop talking it.
—  Maya Angelou
There is so much anger in me
fury ripping like cannons
through tissue and bone and time
it’s poison, I know it
I can feel it dripping into my organs
burning and killing with acid necrotic
where do I put it so it won’t eat away
everything I am from the inside out?
I’m so afraid I’ll just erupt into flames
the second someone lights a match
to light the way
—  I’ll burn like a torch if I can’t spit this out /.w.m.w.
Not one day in anyone’s life is an uneventful day, no day without profound meaning, no matter how dull and boring it might seem, no matter whether you are a seamstress or a queen, a shoeshine boy, or a movie star, a renowned philosopher or a Down’s-syndrome child. Because in every day of your life, there are opportunities to perform little kindnesses for others, both by conscious acts of will and unconscious example. Each smallest act of kindness—even just words of hope when they are needed, the remembrance of a birthday, a compliment that engenders a smile—reverberates across great distances and spans of time, affecting lives unknown to the one whose generous spirit was the source of this good echo, because kindness is passed on and grows each time it’s passed, until a simple courtesy becomes an act of selfless courage years later and far away. Likewise, each small meanness, each thoughtless expression of hatred, each envious and bitter act, regardless of how petty, can inspire others, and is therefore the seed that ultimately produces evil fruit, poisoning people whom you have never met and never will. All human lives are so profoundly and intricately entwined—those dead, those living, those generations yet to come—that the fate of all is the fate of each, and the hope of humanity rests in every heart and in every pair of hands. Therefore, after every failure, we are obliged to strive again for success, and when faced with the end of one thing, we must build something new and better in the ashes, just as from pain and grief, we must weave hope, for each of us is a thread critical to the strength—to the very survival of the human tapestry. Every hour in every life contains such often-unrecognized potential to affect the world that the great days and thrilling possibilities are combined always in this momentous day.
