...telling them they can't do it...
Take a look at this face. This is the face of that little voice. It's a whining, miserable brat who's not getting enough attention and plans to make you pay for it. Misery loves company. Feeling crap? Make someone else feel crapper. Works every time.
But that face is also a bit scared underneath (ok, pretty damn deep underneath in this particular case) - what if you try something and it all goes tits up? What if you look stupid/get hurt/fail miserably?
Well, Little Voice - WHAT IF YOU DON'T?!
That little voice needs to be sent to their room without any supper (you could maybe pop up later with a sandwich - I'm not cruel) and left to reflect on what they could've done, had you listened to them. They COULD have stopped you achieving your greatest ever success, stopped you reaching your goals and made you as miserable as them. But they didn't.
BECAUSE YOU IGNORED THEM!
Happy writing, living and loving today, and may the only voice in your head be a positive one.
