This is not a contest between persons. The humblest citizen in all the land, when clad in the armor of a righteous cause, is stronger than all the hosts of error. I come to you in defense of a cause as holy as the cause of liberty - the cause of humanity.
There is an element of luck, there is an element of trial and error, sometimes you fail, sometimes you succeed. It's not as beautifully simple as it may seem when we are talking about it.
Action and reaction, ebb and flow, trial and error, change - this is the rhythm of living. Out of our over-confidence, fear; out of our fear, clearer vision, fresh hope. And out of hope, progress.
Well, I don't think a specific role can destroy your voice. What can destroy your voice is when you... make an error. Everybody can make an error. But then you need to realize what is your way.
