Three years into being a reporter, I am still every bit an amateur, if not more.
I have learned, for example, that my stock knowledge is, more often than not, old stock and needs replacing with fresh ideas and new ways of thinking. And that is why when senior reporters talk, I take notes as often as I can without offending them.
Above is a sample of notes taken in between beers, which, apparently, is the currency of choice among people who work in journalism. A lot of it is common sense, really. Know your beat inside and out. Offer insight instead of just output, etc.
Sometimes, it is common sense couched in a Bible verse:
Wisdom is the principal thing; therefore get wisdom: and with all thy getting get understanding. (Proverbs 4:7)
Quoted to me by an atheist reporter who got it from Forbes magazine.
