In 1990, Nelson Mandela told ABC that his time in prison had its benefits:
"To spend 27 years at the prime of your life is a tragedy . . . but there are very positive aspects, too, because I had the opportunity to think about problems and to reflect on my mistakes. I also had the opportunity to read very widely, especially biographies, and I could see what men — sometimes from very humble beginnings — were able to lift themselves with their boot strings and become international figures."
