“The difference between passion and addiction is that between a divine spark and a flame that incinerates. [..]
Passion is divine fire: it enlivens and makes holy; it gives light and yields inspiration. Passion is generous because it’s not ego-driven; addiction is self-centred. Passion gives and enriches; addiction is a thief. Passion is a source of truth and enlightenment; addictive behaviours lead you into darkness. You’re more alive when you are passionate, and you triumph whether or not you attain your goal. But an addiction requires a specific outcome that feeds the ego; without that outcome, the ego feels empty and deprived. A consuming passion that you are helpless to resist, no matter what the consequences, is an addiction.”
