It sounds a bit corny, but an idea to turn off the radio voice is to write down a list of things you like about yourself. The first thing I wrote down was
"I am committed to personal growth."
Once I had written that down, I knew I was on to something. If you look at it, that statement is perfect. It is confident and optimistic, but it is not like saying "I am smart and good-looking." It acknowledges any weaknesses that might be there, implicitly.
Then I wrote:
", and I have already made progress; I have shown that this growth is possible, and I am not done yet."
Then I wrote some more things. Some more specific and others equally general. I tended not to write things like "I am a good writer." I think I am comfortable with listing things I am good at, but those things don't tend to dig as deep. I could easily discount a thing like "I can make a good omelet," because it doesn't seem as powerful a statement as "I am committed to personal growth." Lots of folks can fry an egg, after all, but how many are as truly committed to personal, intellectual, and musical growth as I am?
But if you want to start off with just things you are good at, that's fine too.
I have a friend, not a close friend yet but a relatively new acquaintance and part of my larger circle of friends. He is relatively young, tall, good-looking, and personable; he's read a lot of poetry and is very bright. He is smart and easy to talk with, etc... I was thinking, yeah, he's a great guy, it would seem, involved with his children's activities and someone most people would like.
Then the next thought was that I am all these things too (aside from tall and young!). So I sometimes use that as a device to ease up the pressure on myself. Why should I be harder on myself than I would be on my acquaintance?
