Do you love what you're doing or are you doing what you love?

Remember when you were younger? You had great hopes of doing something big. The more you thought about it you radiated from the moon & back. Your smile of joy was bigger than the sun itself. As we get older life became a reality. We turned in certain directions which have impacted where we are today. Many of us are riding the line of the comfort zone accepting the waves of life. The terminology is "settling." Have you adopted a more steady or secure style of life, especially in a permanent job and home? Do you love what you're doing in your career or are have you followed your goals to doing what you love? Would you change anything?
Doing what we love attributes to a more healthy, stress less, vibrant life.
