A year or so after his split from Gwyneth Paltrow, Chris Martin says he has a new lease on life.

"A few years ago I was in a low place in my life and was feeling kind of down and confused," the Coldplay frontman admitted on Australia's 2DayFM's "Rove and Sam." Martin says it was the book, "Man's Search for Meaning," and a poem called "The Guest House" by an Afghanistani poet that caused him to start looking at the world differently.

"Those two things started me off on this whole journey where I just feel so happy to be alive," he said. "That may sound a little simple but I suddenly feel very grateful to be alive. If it's coming across then that's great to hear."

Martin, 38, and Paltrow, 43, were married for 12 years before the actress announced their "conscious uncoupling" on her website in 2014. The two have a daughter, Apple, and a son, Moses, and seemed to have remained friends after their divorce.
