The Belgium international's only starts since April have been in the EFL Cup but he came off the bench after Philippe Coutinho's serious-looking ankle injury to make a crucial breakthrough in the 2-0 win over Sunderland which kept his side in second place.
Origi has had Roberto Firmino and Daniel Sturridge ahead of him in the pecking order but took his chance when it came along, suggesting he has not lost any confidence either.
"You have to stay patient in a positive manner but to be honest it has been very difficult," he told reporters.
"As a young player - as a footballer - your life is football. When you're on the pitch you enjoy yourself and when you are not on the pitch you have to accept it and you have to know it is a professional world and we have a very good team.
"You have to stay positive and believe in yourself. You never know when the team will need you."
"I worked a lot to stay sharp for when I can help the team. We have a strong squad and everyone is important.
"I showed I am very hungry and willing to make the steps to help the team for the rest of the season."
