So really it is a game of balance...The key to financial success IS volume. Make no mistake about it. All, as in ALL, with out exception, the indy authors that I have spoken with that make a full time living doing this have a large catalog of books. It is a numbers game. When your selling books at a few dollars a pop, and only taking home maybe 60%... you need to sell a lot of them to make real money.
On the flip side is the books have to be good enough to sell. They need to be readable, and have a market where people enjoy them. Bad books do not inspire people to buy more of your books, or recommend your books to others.
So if your goal is financial success - you need to produce as many books as YOU can as fast as YOU can while keeping them of a GOOD ENOUGH quality to sell.
If you are writing for enjoyment, you can take more time and produce better books at a slower rate and maybe one day far off you will produce enough quality works to pull in some cash.
Well this post is entirely my opinion, and I do not claim to be an expert, I am sure I am right. Otherwise it would not be my opinion.
