The octogenarian, whose political career spans over five decades, said wishes pouring in on his birthday have encouraged him to work more. "Birthdays are an important milestone in one's personal life. My 50th, 60th and 75th birthdays have been celebrated publicly. Even though I didn't want a celebration on my 81st birthday, I have come (to the event) because the party wanted," he said. "December 12 is an important date for me not because it is my birthday, but because it is also my mother's birthday. December 12 is also the birthday of my nephew and niece. Pratibha's (Pawar's wife) birthday is on December 13," he said.
