The Chelsea midfielder has not always been a popular choice for the Three Lions despite his impressive club form, but has always been available for selection.
The 34-year-old netted a brace in the 5-0 win in Moldova on Friday, and Lampard admits that he is happy that he persevered with his England career.
"I am very proud of my England career. With England careers, they can't always be rosy for any player especially if you are going to get towards 100 caps," said Lampard. "I am very proud of the games and the goals I have been involved in. The only downside is that we have not won anything. That's something we all want to put right.
"I am pleased I didn't bail out when I was getting stick because there can be easy routes particularly when you get to 30. You are allowed to retire from that age onwards.
"I was never interested in that. Whether I carry on playing one more game or 15, I'd like to think people will say 'he was really proud to play for his country and put in a good contribution'. If they say that I will be very happy."
