Your internal mediocrity is the moment when you lost the faith of being excellent.

Early from middle school，or evem from primary school, I admit I couldn't exceed others when I can't nail my study and duty as a monitor. I doubted myself and I was really wrong. I don't know that much and I should just learn more to have a big vision. Vision is not related to background. You may have no money, you may have no support from your family, but you can choose to think, to persure for excellence. You will never have a second-class lifetime.
