Isaah Berlin asked the question in a famous essay and people have been repeating it ever since.
Are you a hedgehog, i.e., someone who has one strategy that they apply to every situation, or a fox, i.e., someone who has many possible strategies? If you're like me you probably consider yourself a fox in this respect but it's possible that friends who know you would disagree. That's not necessarily a bad thing. Hedgehog atrategies are suprisingly effective.
The most high-profile hedgehog I know of was General Patton of WWII fame. Pattin often took command of units that were demoralized from innaction. The previous command was usually mired in the bog of too much information. They had conflicting intelligence about the enemy so they did nothing while they tried to sort it out. Patton would take over and immediately order an attack. Morale would shoot up immediately. Automatic attacks may seem like a dangerous strategy but Patton rightly figured that bad morale was a greater threat than a formidable enemy besides, if the enemy were so strong why hadn't they attacked before now? Hedgehogs are blessed with certainty and self-confidence and that's a big asset.
