The secrets i hide

Today,when i think of my friends, the secrets that i hide,  my mind flew

I always think, everytime, in this repeated cycle of life.
What do human really strive for?
What is the hardest thing to achieve? What i think is -secrets.

Human have surpassed boundaries, every obstacles that god had cast upon them, they have achieved everything there is, technologies, knowledge. 
Exams, there have been so many people that had already achieve the best results.
Money, human too have succeeded in that.
Boundaries, human explored the deepest seas, furthest space.
Yet, what that cant be resolved are secrets.........human are still searching the secrets of the space, nano-scopic organisms, for myself, i keep alot of deep secrets in my heart.

I never showed my real self to anyone......
I always wear a mask,
Every mask hides a secret,
I hid my emotions as though i am void
And yeah, i think secrets are the hardest thing to keep and to get
eventually they will be exposed in an emotional rush...or rather willing-ly..........
I sometimes feel guilty though,
Lies that i gave to my dear friends
Lies are made to keep secrets
Lies are bound to make u guilty
Well, that's the burden i have considered to bear
