I've recently gone back and perused J.A. Konrath's older blog posts on his Newbie's Guide to Publishing. If you're an indie author and haven't read Konrath's blog, I highly recommend doing so, otherwise, you're missing out on some great information.
During my reading, I've come across several posts where he talks candidly about the emotions new authors experience when they first start out in this business. It's refreshing to know that I'm not alone in my self-doubt and frustration. Nor am I alone in my obsessive tendencies to Google my name and check my sales stats on my various distributors' websites repeatedly throughout the day. While these affirmations are nice, the most valuable insights are learning from his experiences with self-promotion.
While I'm ignorant about advertising and marketing, it's nice to know I can go somewhere to learn from someone else's mistakes and successes. Especially, someone who is succeeding in the field of writing. More often that not, when I feel depressed about my low sales, feel like I'm a voice quacking in the void, or that I'm just another face in crowd, I can read Joe's posts and begin to feel better about the things I am doing, gain a sense of motivation, and know I need to stay the course.
