"I've never done a job for too long," he said. "I think that there should be cycles in life and in work and I think they (RTE) would be about as interested in seeing me there for 30 years as they would in seeing a particular Taoiseach in the job for the same amount of time.
"I don't see it as the end at all. I'm 36. I've got this job that is indeed a dream job.
