I didn't so I haven't but, I am planning this for a long time but I just can't execute it.
But I keep wondering: what does it take to turn all that into something real? Like, how do you go from idea to book without totally losing steam halfway through?
How about by just writing it and looking for the steps and guidelines on how you'd do it.
I think that I've seen some guidelines from udemy or such websites on how to publish one. As long as you've got your write up already, publishing will be easy but of course it comes some investment on your side to pay for the publisher.
It's also likely that the publishers can help you by giving some idea, I haven't contacted any though.
