Call me a hater, but I think a huge majority of FM radio presenters are not to be taken seriously. It is possible that many of them do not take themselves seriously. The tragedy is that many people do. These guys do this thing for entertainment, for it's "fun" value. To think they are an inspiration, that there's any wisdom to be gleaned from their chatter, is, my friend, to expect milk from a chicken.
Learn first to treat your time as you would your money, then treat your money as you do your time.
