Solution to Yesterday’s Presidential Sudoku

Yesterday’s Presidential Sudoku puzzle asked you to spell out a U.S. President's quote, given this clue:

A President of the United States was born on this day, 2/6. He was 69 years old when he was inducted into office as the 40th President.

The answers:
“There are no constraints on the human mind, no walls around the human spirit, no barriers to our progress except those we ourselves erect.”
Ronald Wilson Reagan
