I still find it surprising how easy it is to become inspired by "negative emotions" like anger and rage. Channeling such raw being into a means to an end, one can find their goals vastly closer to reach, or easier to obtain.
The N.E.s happen to be the marks that start much for people, regardless their age or any other features.
I, of course, have complete control over my emotions, and never let them ruin my works or projects. As that would be completely unprofessional.
