In its excellent Jury Expert blog, the American Society of Trial Consultants offers good advice for trial lawyers:
Rehearse. A lot.
As the authors explain:
Experienced trial attorneys make it look easy. Rest assured, those attorneys are the ones who rehearse the most, privately and publicly. “Off the cuff,” is a romantic ideal, but is not a method for experienced trial attorneys. Attorneys who do not rehearse use the stress related adrenaline rush as a means of creating energy for last minute preparation. Feverishly finalizing content and supporting visuals throughout the night does not produce a persuasive performance.
