Controlled Aggression

Last burst. We as rowers seem to be in desperate deficit of it. Yet, when it comes, it sometimes gets us in a mess. We screw up our race because we go berserk.
Sometimes I feel that we are professing a doctrine of hate, because we have to sum up our emotional state and hate is the one that brings out aggression best; but is hate the only emotion that can bring it out?
What happened to desire, passion and the spirit of competition?
Perhaps, that is what is missing. Yet, some of us can bring out the aggression just fine but can't control it. Layman terms: we lose our cool.
What we have to realise is that, apart from the last burst, we should take the entire race as one long last burst. That being said our goal is to make sure that our output in each stage to sufficient to ensure maximal perfomance. We do not expend all our energy in the starts, nor do we leave everything to the last burst.
There must be a certain amount of control to regulate the psyche or we die out physically while our mental engines are still ready to go.
Go berserk for your race, but do not lose focus or control.
For a illustrative analogy of controlled aggression please ask this year's J2's I'm sure they have one appropriate analogy to tell you.
