Throughout a career, there are often situations where decisions are left to the individual.
Having played competitive tennis, I have acquired the notion of making quick and decisive choices.
These situations have clearly shown how useful it is to discuss and evaluate cases with one's coach in order to make accurate and appropriate decisions.
