The US international, who was recently named U.S. Soccer Male Athlete of the Year, helped Fulham beat Newcastle 5-2 with his goals on Saturday.
However, the 28-year-old insists that he is not finished there and will be striving to carry on scoring goals for Martin Jol's side.
"I always want to better myself from the year before," Dempsey told Goal.com.
"Goals seem to come in waves. I'm just trying to keep working hard and keep enjoying the moment while I can because sooner or later they dry up on you.
"Hopefully I can keep continuing with this form as long as I can because one of my favourite parts of the game is scoring goals."
Dempsey has 15 goals in all competitions so far this season.
