Hmmm. What is there to say? Well... You want to make people feel their feelings. If it's funny, make them laugh, if it's happy make them smile, if it's sad make them cry. Honestly, I can't really tell you 'How To' do this, you just do it. You have to make it part of yourself to write something that'll make people feel their emotions in a high level.
If you REALLY want to do this properly, you should talk to people on what makes them laugh, smile, and/or cry. Try to make them tell you what gets them in touch with their emotions. For example: Funny- "You bet my sass I am." Happy-"She smiled as though it were her happiest moment." Sad- "It felt as though it were the end of the world. It crushed me into pieces." Or something along those lengths.
If you really want to dig deeper, think about what gets YOU into deep emotional states. Is it a cat falling off a chair, your loved ones, and your dead dog? Who knows, I'm not you. What you absolutely need is for the characters to feel these things with the reader. To do so, have dialogue and inner thoughts through the main characters and the characters around s/he.
DON'T TAKE ANY ADVICE FROM ANYONE! You don't even have to listen to me, but just a kid with dreams (kind of like everyone else). But if somebody tries to tell how to write your book, or what you should write, DO NOT listen; it's terrible. You are who you are and so is your writing. Don't be afraid to change things in the writing community. Write about something that hasn't bee written before! Example: When you die you see GAME OVER and two options underneath- Continue Defeat or Start Again.
Put that in your pipe and smoke it! That's a great idea, and if somebody says 'That might be offensive to some religions blah blah blah'. Ignore them. They don't know anything about how your mind works its ways around.
This isn't really a cheat sheet on how to do something, but I think all of you should know.
One of the biggest problems I have when starting a new book is getting over the one I just finished. My mind will still be in the other book's universe/world and I won't be able to concentrate on the writing at hand. My advice for you is to take a break of writing for a while and think of the world you are going to create next. Don't be stuck in something you've already finished, it's not fun.
Step 1) STOP WRITING!! I know this might be hard, but just go on YouTube and watch adorable animal videos for nine hours. That's what I do.
Step 2) Start with the main character of your next story, and then create the world and other characters around them. Don't write it down just yet, keep it all inside your head.
Step 3) Keep your idea in your head for at least a week, and think of ways you could write it down.
Step 4) Force yourself to write it down. By this point, it will be terribly hard to write down this world on paper. Sorry.
Step 5) Go back to the ugly you've written and edit out the rough patches to make it sound better.
I hope this helps with some of the problems people have with getting over a book.
this is where i ramble; have fun
