Share 'Dark side of writing'

I was recently giving some advise to a new comer author. One thing I tried to do was highlight the dark side of being a published author, for example: - Tons of rejection letters you need to put under your belt - Worry that the next book reviewed will be as good as the last - Hours taken away from other life pleasures. You guys/girls got any to add? Michael Davis Davisstories.com
