It may sound like a completely obvious thing to say, but it is important that you understand how radio works.
Some radio is good and some is bad.
If you think that everyone who works in radio is just waiting for their chance to break into television you d be very wrong. I have found that people who work in radio are more passionate about what they do than their colleagues in any other branch of the media. They are passionate themselves and they demand it in others. So, if you don t listen to the radio - if you don t even like radio very much but think it might be a short cut to a job in TV, either learn to lie convincingly, or choose another career. Built Programmes BBC Radio 4, BBC World Service, and to a lesser degree BBC Radio 3 and 2 produce built programmes.
