The Australian Open champion said: "I did lose my temper but sometimes, in my case, that helps, even though it doesn't look great."
He added: "It was frustrating, I cannot lie, but I came back from it and I'm not going to change who I am.
"I can work on some things, but my temper is my temper. My character is my character. You have to try to take the best out of it, not change it."
Djokovic admits he will have to up his game to win his first Wimbledon.
He had to dig deep to beat Baghdatis and was second best on many occasions to the Cypriot, who enjoyed the occasion thoroughly by lapping up the support of the fans.
Djokovic was impressed with the 26-year-old's performance and the atmosphere on Centre Court.
"I have been here a few years now and in that time there were not many moments when I saw practically all the stadium on their feet," Djokovic added.
"It was incredible. It was exciting to see the Centre Court of Wimbledon being so enthusiastic about the match and for me as a player, I have to appreciate that and be happy I was a part of the exciting match."
