If you podcast long enough, you're going to get criticism or negativity. You can't create work and share it with the world without experiencing it.
One of the things we say in the Community is that you haven't made it until you've got haters. If people feel strongly enough about what you're doing to love it, then someone is going to feel strongly enough to hate it, or at least severely dislike it.
I'm still pretty unknown, and I know that because I've only ever received negative feedback once. I could say that I just brushed it off, but it did affect me. Instead of letting it get me down, I sat with it. I thought about it. I analyzed why it made me feel the way it did, and I asked myself why.
I want to share what I've learned about feedback and criticism to help you learn how to process it when it comes to you (and it will), but also to help you give feedback more effectively and waste less time engaging with people or on feedback that doesn't really matter.
