Izuku is a quite diligent and strong-willed student, being extremely (and sometimes scarily) enthusiastic about topics related to heroes. His dream drives him to write down notes about everything he learns in regards to heroes' Quirks and fighting capabilities. Thanks to this practice, Izuku has developed a great analytical mind and can form complex battle plans in a few seconds, factoring in the best ways he can utilize the Quirks of allies and enemies alike for his own advantage.
