The number one seed faces Juan Martin del Potro in the semi-finals tomorrow for the opportunity to take part in his second final at the All England Club.
Djokovic told reporters: "I'm trying to use that experience that I had in the past, especially in this tournament in 2011, to feel comfortable and calm and confident towards the end of the major tournament.
"Now I'm in the semi-finals. Hopefully I can go a step further. I'm really going to try to step out on the court in two days and give my best to be in another final of Wimbledon. I believe I can make it."
The 26-year-old won Wimbledon in 2011, beating Rafael Nadal in the final.
