Let me take a remote scenario and ask you to make a tough choice.
You’re a relatively unknown author with the opportunity of being published.
The publisher likes your book and offers you an advance.
You have two choices –
Take a large advance, or ask for a smaller advance.
The things to remember are that you are relatively unknown, and this is an advance on the book sales, you won’t see any more cash until the advance is paid off.
What would you choose?
I would go for the lower amount as it is paid off quicker.
