You're allowed to think and share your thoughts. And you can do it in whatever medium suits you — books, tweets, vlogs, blogs, or a megaphone on a busy street corner. Amurrrica.
I forget this all the time. I usually forget it shortly after I've committed some considerable length of time to thinking about something, right in the middle of putting my thoughts into words on a screen. I lose confidence just as I'm figuring it out. Funny. But this is what we're supposed to do, think and share ideas.
Sometimes the worst ideas on a subject come from the people closest to it.
We need an outsider's perspective, they say.
Well, you're in luck, for I have extensive training in the subtleties of being an outsider. Many of us do. And many of us do share our thoughts these days, but it's only the careless ones who seem to do so shamelessly. It's the ones who are worried whether or not they have earned the right to contribute who should. Outsiders get obvious things wrong, sometimes, of course. But that's not the point.
The point, I think, is, provided you're not trying to pass yourself off as more of an expert than you are, you're allowed to contribute to any topic of discussion. Please share your ideas. You're encouraged. Your's might turn out to be the outside perspective that was needed. You might fall on you face, too. That's ok. Experts fall on their face all the time.
You'll at least have an excuse.
