Optimist, pessimist or a realist?
Those options are too limiting.
In the fact that I am often pragmatic, I suppose I lean towards being a realist.
In the fact that I fully perceive the ill we humans do ourselves and the earth, I am a pessimist.
In the fact that I yet continue to live an breath, and can fully perceive the love, kindness, compassion and hope we are all capable of, I am an optimist.
But I am seldom more purely one than the other and as life is lived all three remain in a constant state of flux with each other.
Learn as if you will live forever, and live each day as if it were your last.
