I don't know who Scot Ventrella is and I've never read the book from which the following quotation was taken... but I sure like it!
"A friend of mine, Olga, has developed her own personal definition of success. She says that 'Success is when you are happy to go to work in the morning and happy to come back in the evening , and you are very welcome and liked in both places.'"
(I got it from Guideposts. They got it from Mr. Ventrella's book, "Me, Inc: How to Master the Business of Being You".)
