As someone whose angling writing career has run in parallel to Kevin's yet broken into print there is obviously something missing with what Kevin is writing. I did close on 250,000 words on Fishing Magic (200 articles but averaging more than 1000 words), then found a way to get published with two book publishers - three jointly written and three solo efforts, of those six three have gone into reprint - and articles in several magazines and the weekly papers - about 500,000 words in print. Kevin writes well - no problem there - but needs to identify where he can make his mark. There are many types of angling writing from the technical instructional where you need to know your stuff through story telling, humour, biography, anthologies, and, as Martin Bowler once told me and really summed it up (apologies for the name-dropping) 'it's show business'. The object is to entertain, enthral and educate; do that and you will succeed but it means spending a lot of time researching what the readers want.
Changing the subject slightly, what Graham Elliott described as 'vanity publishing' is in his case self-publishing; he took the risk with his own money but controlled the sales which repaid his costs and hopefully made a few bob and nothing wrong with that. A friend of mine has used Lulu.com to publish some books about his favourite rugby team - he hasn't made any real money but it hasn't cost him anything either. The vanity press latches on to hopeless novelists and poets and takes their money - many thousands - with promises that the book will sell which it doesn't and the failed novelist/poet is left with a few copies of a dud and no chance of recouping their outlay.
