To be optimistic is to see the proverbial glass half full. For me, optimism is seeing the sun rising on the horizon and
setting at the end of the day; it is a full moon lighting up the sky at night, and the smiles of my children when I come home.
Optimism is hope; hope for a new day and the promise of something better awaiting all of us in the future. For those of us treating cancer, optimism is where we stand right now as the mechanisms and biology of cancer and cancer progression are being better elucidated, which will hopefully lead to shifts in the characterization of this disease and even better, more tailored, more personified, approaches to treatment.
