You are training on Oa with Hal Jordan. Hal made a construct of Sinestro. You start to panic and you make a shield construct. The Sinestro construct starts hitting your shield construct and it starts to crack. You start to panic and think you're losing and suddenly your shield construct shatters. Hal sees this and the Sinestro construct disappears and Hal flies to you.

"You can't doubt yourself. This ring is meant to help defend people that don't have the willpower to defend themself. This ring doesn't give you willpower. It help you channel willpower. Have a little faith in yourself." Hal says hitting you in the shoulder.
