Don’t worry about failing.
Worry about not failing enough. When your biggest fear is how your work or project is going to be perceived by others, it’s easy to delay making any real progress.
When something becomes important to you, it’s easy to fear sharing it with others. You worry that something you care so much about will be shot down in flames. So it’s easier to hide or keep working on things in the shadows.
Bring the work into the open, into the light. Yes, it might fail.
But without that failure, you can’t move forward.
You can’t ultimately succeed.
