I try not to, but I usually can't help myself. I think the ones that are the most helpful are the three star reviews. That's someone who is your target audience, who found a lot of things they liked, but didn't like everything. That's where I can find real, honest advice that can help me become a better writer. With 1 and 2 star reviews, it often just meant the person didn't gel with your writing style, and you have to remind yourself that's okay! Everyone has different tastes. But it can be emotionally draining, for sure.
I always thought my first success would be a floodgate that would open the doors, and everything would flow from there! Instead I learned the process never really stops. You have to keep putting yourself out there, over and over. It isn't an easy career choice! You open yourself up to a lot of criticism about something that is so precious and close to your heart. But it's worth it.
I've never been "recognized" by my face, but I have had someone recognize my name once or twice. I'm always utterly stunned and beyond thrilled!! There's seriously nothing like that feeling of realizing A STRANGER READ YOUR BOOK AND LIKED IT!
