Don’t worry, someone is listening to you. Even when it seems like no one hears or cares, someone is listening. It could just be one person, but that person really needs to hear what you have to say, and you never know what great things may come of it.
So go ahead. Write that post; upload that video; post that photo; make that comment. Someone is listening.
Speaking as someone who’s many times been the reader, hearer, viewer of that post or comment or video that almost didn’t get made. And felt saved by it, and taken it and run with it.
Speak! Share your unique voice. Someone is listening.
