Workaholism is also adequate except that in my case I strive excessively in EVERYTHING I do - whether it be work, a new fitness regime, my relationships or even my efforts to improve my health. No realm of my life is safe from my compulsive perfectionism and desire for achievement! You're totally right that workaholism becomes self reinforcing because of the accolades that one achieves. I'm glad I finally realized this and am breaking the cycle. Thanks for your insightful comment!
