The England midfielder was on the scoresheet in Europe's premier competition for the first time with the opening goal in Chelsea's 2-0 quarter-final first leg win over Porto and was delighted to break his duck in the tournament.
Mount told BT Sport: "It's about time it came. I've been waiting patiently. It was a good time for it to come. A good pass by Jorginho, I had space and I hit it.
"I'm always working on it [finishing]. I don't think you can work on it enough. I think I can improve on it and score more goals."
Ben Chilwell's late goal saw Chelsea take a huge step towards the last four but Mount is wary that the Blues still need to finish the job in next week's second leg.
He said: "We knew it would be a tough game. We kept going, we got the goal in the first half and the second secured a good win. It's only half the tie, there's a second leg to go.
"He [Ben Chilwell] showed great composure. I thought he'd shoot in front of goal but he took it past the keeper. He'll be buzzing with that.
"The job's not done. They'll fight for the next leg and we'll have to give it our all. We'll be ready."
