Speaking to The Sunday Telegraph, the conservationist and broadcaster said that such complements had a positive impact on him.
"The most touching thing is that people say to me that I have had an effect on their lives," he said. "You would be surprised at the number of academics who say things like, 'I didn't realise what a sponge was until I saw a programme of yours'."
Attenborough, who joined the BBC in 1952, added that he is "very relieved" that the broadcasting landscape still offers "room for the sort of television I make".
However, he also voiced concern about how much today's children know about wildlife.
He said: "Talking to teenagers and so on, I am amazed that they don't know things about natural history that I knew.
"I'm sure they are equally amazed that I don't know as much about Twitter, communications, computers and nanotechnology as they do."
The BBC is reportedly planning to celebrate his 60 years at the corporation with a special programme. His new seven-part series Frozen Planet is due to air later this year.
