You could try writing books for children (have you seen the cost of these!!) But you would then need a publisher and possibly an illustrator, unless you are artistical. I have written three books, two novels and a shorter thing, which are published on Amazon, but I wouldn't recommend that, unless you can tap into a market. I have "made" a whole £66 since 1st April (i.e. this tax year), woo I'm rich, a whole tank of petrol!
