It makes or breaks you, my friend.
Have you ever picked up a book, loved the cover, loved the back cover and opened it to the first chapter only to put it back after the first paragraph?
Why did you put it down?
I bet I know why. It didn’t grab you by the junk and scream “Read me!”
If your first paragraph is weak, readers will assume all your work is. Bring your A-game, boys and girls, and make that first chapter sing.
Ask yourself, am I starting too early?
Do you have a good, solid critique partner/group that will rip it to shreds and offer mind blowing advice?
There are many elements that help engross a reader, and not everything works for every person. The better that opening is, the more people you will appeal to. After all, you catch more flies with honey than vinegar, so set your trap wisely, my friend.
