Terror of the blank screen

You know what it is?

There are moments when it isn't our race, religion, orientation, or some feeble glass ceiling.
Sometimes we are too scared of having the right idea, of making it big, of being right.

We sabotage ourselves.

We tell ourselves, not explicitly but definitely intentionally, that we can't do something, that we will be wrong, or worse: that we will be right.

Why?

Why are we afraid of what we can do?
Why do we hold ourselves back?
Why are we terrified of our own brains?
Why are we scared of being right?
