The voices in my head that hold me back

Here's an incomplete list of the voices in my head that come up when I want to do or create or say something:

• That's not really important or necessary
• It's a dumb idea anyway
• It's naff, people are going to laugh at you
• Who do you think you are?
• You don't know enough about that
• There's something important that you don't know that makes everything you believe wrong
• There's no market for that
• You suck at selling anything
• You have no sense of what people want
• People don't want to be around you, you're disgusting and insecure. Please just stay away.
• You talk too much about yourself.
• People have no interest in what you have to say
• You're not interesting
• You're too much
• Your sense of humor is not funny
• People are tired of you
• Shouldn't you rather …
• pay off your debt
• study some more
• work harder
• take more responsibility for your kids
• get your shit together
• Are you serious?? Now you've just proven yourself as being insane/untrustworthy/idiotic and no-one will never ever trust you again or have anything to do with you again
• You have no right to do/say that

Recognize any? What are yours?
