Who is the real you ?

When you are feeling good, you will be calm and humble towards everyone and you do it cause you hate to be arrogant or rude to anyone.
Your guards are down, you speak to everyone and you want to help everyone.
But when down, you go through a different kind of emotions, what you do is 'suspect' everything and have major 'trust' issues.
You wonder if you have let your 'guards' down for long and introspect hard and you conclude you have been too kind and thus, ended up being too soft.

Trust these phases just come and go i.e being 'up' and 'down', and you run through the same emotions i.e confiding to people when doing good and then being secretive about yourself to people around you when down.

Now, the irritating part in this 'up' and 'down' phases, is that you are so lost in identifying what behavourial pattern is 'your' pattern i.e to be honest and approachable for others or to be conniving and behaving in a smartypants' manner.
I think this search for 'yourself' will go on and on, until we disappear from this planet earth.
Guess, there's nothing like the 'real your behaviour', you always end up fluctuating from one end of the spectrum to another i.e being happy and being sad.
But I think in spite of knowing the result of the contest i.e "you don't have a characteristic behavioural pattern",
I guess we still try very hard to classify as 'introvert' or 'extrovert'.
Can't believe how silly these words sound, when someone calls himself/herself either a 'introvert' or 'extrovert' !
