Ego

"past glories are poor feeding" -Foundation series by Isaac Asimov

"Ego is an evil thing. Confidence is important, but ego is something false. Humility is the way to build confience, and ego is hugely dangerous in this sport, because if you're running on ego you aren't running on good clean emotions, or cause and effect. You bypass it to support a false idea. It's all garbage, the ego is garbage." — Frank Shamrock
