Advice: Don't put too much of yourself into your writing

If there is one thing I learned while writing short stories and starting to write a novel is that putting too much of yourself into something you write doesn't always work and doesn't always appeal to your readers.
Yes, it's fine to distinguish one of your characters with your qualities, flaws and maybe something really exciting that has happened to you and you want to share with the world, but writing too much about yourself into a fiction piece will not work.
Why? Because, let's face it, you as an individual, unless you've been to war or experienced a truly traumatic event, will not have a story as interesting as a "fictional" character you can mold and turn into anything you like.
If you want to tell your life story, wait till you are famous and then publish it as non-fiction. Till then, let your characters be free, don't assimilate them with you.
