You’re afraid to move forward because you’re afraid of criticism, well-meaning or otherwise.
You’re afraid of criticism because you’re too attached to the ideas you generate, rather than as the generator of ideas. Being a “generator of ideas” doesn’t excuse you from generating bad ideas. Bad ideas are as unavoidable as death.
The best way to move forward is to recognize this duality. To show up to create something, share it, and bear all the mockery, nitpicking, and critique.
