Who am I?

For those who may think that I am a fool
And those who think that I am not
I take a deep breath and say with all my heart
not even I know what I am or what I’ve got.

And when the day of the truth comes
I can assure with my raised head
That I've lived my life to the limit
I've lived my life as I really am ...

I don't pretend to be understood
I'm not saying that you must like me
I am what I am whatever that is
and for those to whom I am not, I’ll be ...

I will keep being me, whatever that may be!
