One of the greatest possible sins would be to return to God the life which he has given us with our abilities undiscovered and our talents undeveloped an unutilized. One of Jesus most bitter rebukes was given to him who buried his talents in the ground.
I always encourage authors (especially new authors) to be as generous as we are blessed. For one thing, it is a way to help people. For another, it is a seed one is planting for the life of the book. Someone gave it to someone who gave it to someone else.
