It has been said that a huge part of writing is to know when to give out information and when to leave it out. You want to intrigue the reader enough that he’s interested in continuing reading.
However, this is a risk. Too little information can leave the reader confused, disappointed and uninterested. This is where the risk comes in: using literary techniques like red herrings (leading the characters towards an incorrect trail) can captivate or confuse. It’s the cross every writer/author must bear, and its the honing of this skill that takes decades, even lifetimes to master (if it can be mastered; there is always more to learn).
I am still learning, so be patient. If you have an author in your life, be patient. Help him/her. Encourage him/her. At the end of the day, encouragement is what counts.
Thank you for your time.
