Real life can sometimes be the pits. There are schedules, telephone calls, emails, bosses, coworkers, relatives, kids. Wow. So much to do, so little time.
All those things that make an author holler can also be gems when it comes to writing. Have a boss you can't stand? Make him the villain in your book and kill him. Is your sister a nag? Give her monster kids who destroy whatever they touch. Do you have a friend who always brags about everything she has? Have her invest all her money in a company that goes under. Ah, yes, revenge is sweet.
Too mean, you say? Okay, how about the special friend who can't seem to get a fair break? Give her the hero and let her live happily ever after. Do you have the best brother in the world? Let him find his dream job. Are your parents wonderful? They bought the winning lottery ticket!
Do I use real experiences in my books? Of course. I doubt if there's an author who hasn't drawn on something from her/his life and used it in a book. Do I use real people? Yes and no. I borrow from a person's life, but rarely pattern a character exactly after a real person.
You can add the good in with the bad. It's your book, your story, your world. Call on your life experiences, or those of the people close to you, and use them. Add your own personal touch. Real life may be stranger than fiction, but it can also be glorious.
