Preston striker Neil Mellor says he is looking to make up for lost time as he prepares to make his comeback from injury.
The 29-year old former Liverpool striker has missed the last seven games with an ankle ligament problem.
He told BBC Radio Lancashire: "It's been frustrating to miss the amount of games that I have.
"At the time I didn't know how serious it was and it's proved to be quite serious by missing the games I have."
Mellor picked up the injury in North End's defeat at Walsall on 15 October and in his absence the Lilywhites have failed to win a league match since.
He said: "I've been getting really angry just sat at home listening to the away games on the radio.
"Listening to the Charlton game was probably the worst. After 15 minutes thinking it's 0-0, not bad - 4-0 at half-time was a bit depressing."
Preston's slide down the League One table has taken them to 13th position but Mellor says the promotion challenge is far from over.
"There's a lot of games left to play and I'm pretty confident that we're going to get back in the mix that's for sure.
"I was second at Christmas with Sheffield Wednesday last season and we ended up finishing 15th so a lot can happen in the second half of the season.
"I'm hoping that the good run we had at the start of the season will be around the corner for us and we can get back in the top six," he concluded.
