Heck, I generally just post whatever comes into my head here. People can always think, "Well, she's a bit manic today!" or whatever..... Seriously, don't worry about it.

As far as introversion and extroversion, it's not an either/or
way of typing people. And introversion is not the same thing as shyness. Basically, what is comes down to is "Do you get your 'battery' charged more by being out with people or being by yourself?" So, you can go out and be the life of a party sometimes and still be more introverted if you come home and find yourself needing to do something by yourself to get back into gear. The reverse would suggest you're more extroverted. You just really look forward to being with people and can feel sort of "run down" if you can't after awhile.

For specific details, you might read what Carl Jung had to say. As I recall, he came up with these terms.

What you're talking about isn't so much about this issue than maybe about your self-esteem, I suspect.
