I've heard people say before: just be yourself.
Well, does 'just be yourself' mean be the un-confident and nervous person you are?
your real self is not un-confident\ nervous...
the un-confident\ nervous person you think you are is just something you picked up from social conditioning and life experiences.
For example (this is a general example not saying it's everyone's situation):
a lot of men are not nervous at all around women during elementary school and they certainly don't see women as some sort of creatures who are above them.
In fact, a lot of men\boys during elementary school think women are dumb and don't even want to hang out with them.
Then something changes....
Of course there is an hormonal and physical change that creates physical attraction towards women.
but the fact that these men are afraid of talking to women
or see them as creatures above them is not due to the hormonal change. It's picked up with social conditioning.....
so in the example above, for those men: being themselves around women is being the same way they were during elementary school (no fear, no looking at women as above them).
