Yes!!! It's easy to give opinions and judge people from the sidelines. I've done that before. I've also been on the receiving end and it can get really crippling. .
Be mindful of the things you say to people and how you judge. If you're busy criticizing, who's doing your work?
If you're a creative who is crippled by the idea of what people will think of you and you're not creating because of that, remember those who are in the arena get you and they will respond with love. The feedback from those who aren't in the arena doesn't matter. People will give feedback, judge and criticize either way! You might as well have them criticize you for being in the arena and creating rather than just watching from the sidelines!
