My memory often locked and I forget what to say, although I know it isn't really lost.

It often happens to me that I don't come up with anything to write.

No surprise. I often doesn't come up with what to say when I'm asked to introduce myself. It happened so many times that all I could do was stand still, blushing, frozen and stutter when I was asked for some comment. It even happened when all I had to do was saying my name.

Of course, I don't think I really forgot my name, but at least I couldn't say it. This shows that the reason I can't say anything isn't always I don't know the perfectly right words.  In this case, I even know the exact word - my name. (Perhaps I may be embracing the desire that I would have been anyone else. Anyway, when I can't say my name, I often don't like myself very much.)

As well as I sometimes have try hard to say my name, I often have to make extra effort to say what I'm in mind. Knowing right words might help lot, but it can be a double-edged sword. Although it may be definitely necessary to know right write word when you are responsible to explain or report on behalf of someone else, but otherwise obsession with using perfect words (and attempts to show your perfect - in any way -) slow your communication and much likely to hurt your self image.

Even when I'm to say my name, perhaps it may not be necessary to do perfectly all at once. In case I stutter for the first time, there's more likely to be the second, or third time.
