Emotion is short-term; Devotion is long-term.
Emotion is a short-lived adventure; Devotion is a lifetime experience.
Emotion brings you places; Devotion makes you stay in those places.
Emotion gives you a vision; Devotion makes you fight for that vision.
Being Emotional can drive you crazy; Being Devoted can drive you to the OUTER LIMITS!
Once you are emotional about something, ask yourself if you can be devoted to it. If not, then you might be wasting your time. Move on to something that you can be devoted to.
