The word success means different things to people. Perhaps it symbolizes money and what it can buy (a BMW or a Jaguar). Perhaps it signifies personal fulfillment and self-esteem. Often, it is a combination of achieving material wealth and personal happiness.
Wouldn’t it be nice to enjoy what you are doing while the money rolls in? Wouldn’t be nice to work at a “labor of love” rather than to receive a mere weekly paycheck?
