There is a quote by Franklin D. Roosevelt that hangs on the bulletin board in my home office offers insight into what it means to me to be a creative person.
It reads: "Happiness lies in the joy of achievement and the thrill of the creative effort."
I'm not sure how FDR had time for creative outlets during his time as President for a historic three terms. But as a brief read through his biography on Wikipedia indicates, he was a scholarly man of many interests. So it is probably his appreciation for a pioneering creative person from which this quote derives.
