Former WWE professional wrestler CM Punk has announced that he will be joining Ultimate Fighting Championship (UFC) after he called quits at WWE.

CM Punk has told that this was the easiest decision of his life and will debut at the Octagon in 2015.

"It was actually a really easy decision to make. Time will tell how wise of a decision it was. I'm excited. I finally feel there's something I can put 100 percent of myself into and I will get 100 percent back," Punk added at a UFC 181 post-fight press conference, said Bleacher Report.

"This is my new career, 100 percent. I'm going to go full steam ahead, all systems go after today, and it's going to be fun," he told ESPN.

Punk has spent most of his adult life with WWE, eventually quitting it in January 2014. He is now 36 and is ready to challenge himself. He has been practising Brazilian jiu-jitsu for a long time, but his experience in UFC is nil. But that has not deterred him, in fact he has turned inspirational.

"I'm not going to try to give you some inspirational message. There are a lot of kids out there that look up to me, or at least I think there are. I always tell them: do not let anyone tell you that you cannot do something. Choose a path and work towards it to the best of your abilities," he added.

He also added that his wants to make his debut in the middleweight category (185 pounds), but has to lose weight for it. He might also be contesting for the 170 pounds category. He also revealed of a new training schedule that will help him prepare for the matches.

Punk has been compared with Brock Lesnar, another WWE wrestler, who joined UFC earlier. Punk jokingly added he was "cuter" than Lesnar.

He revealed that he was aware of the negative criticism for signing up for UFC, and said he will be off Twitter.
