Former Wales coach Rob Howley admits he feels a need to prove himself again in rugby.
Warren Gatland's ex-number two has become assistant coach of Canada, his first job since being sent home from the World Cup in disgrace over a betting scandal.
Howley told the BBC he has emerged from a 'dark tunnel' and is ready to embrace international rugby again.
"I'm very aware we each make mistakes, are vulnerable to making mistakes," he said.
"I certainly made many mistakes in my coaching career, particularly as highlighted in the Rugby World Cup.
"I'm just thankful I have been given this opportunity by Rugby Canada.
"I feel that I want to prove myself all over again."
Howley was banned for 18 months - nine of them suspended - for bets placed over a four year period between 2015 and 2019 .
"The past 12 months have been very challenging," he continued, saying: "I have learned it's important to talk about those feelings instead of suppressing them.
"Thankfully, through the dark tunnel which I've experienced, I feel I am ready to go and I am looking forward to the challenge."
Howley said he has been helped by messages of support from the rugby world.
"I'm so grateful because it gives me confidence and more self-belief. I am looking forward to being back in the game," he said.
"I do believe in second chances. I know from my perspective as a coach, that players make mistakes, we have selection and give players an opportunity."
